13. R1 first to second floor ratioCity of Cupertino 10300 Torre Avenue Cupertino, CA 95014 (408) 777-3308 Fax: (408) 777-3333 CUPERTINO Community Development Department Summary Agenda Item No. IJ Agenda Date: October 21, 2008 Application: MCA-2008-03 Applicant: City of Cupertino Property Owner: Various Property Location: City-wide Summary: Consider a Municipal Code Amendment to the Single Family R1 Ordinance (section 19.28.060) regarding the allowed ratio of the second floor building area compared to the first floor building area. The revised Ordinance will consider adjusting the allowed ratio to facilitate greater architectural diversity, but will not consider increasing or decreasing the total allowed building area on an Rl lot or changing the required second story setbacks. The Ordinance amendment will also include minor language clarifications relating to gardening activities and miscellaneous wording changes to improve the readability of the document, Application No. MCA-200~~-03, City of Cupertino, Citywide. RECOMMENDATION The Planning Commission recommends that the City Council deny: • MCA-2008-03, citing the need for a more comprehensive design review process for two story homes. The City Co>ruuil may consider the following alternatives: 1. Adopt the Planning Commission recommendation and 'initiate a review of the R1 Ordinance including but not, limited to topics on the ratio of 2nd floor area to 15t floor area, the total 45% floor area ratio and the overall R1 design review standards/process; or 13-1 A4CA-2008-03 - R1 Ordinance October 21, 2008 Pave 2 2. Adopt the staff recommended ordinance framework and direct staff to work with the City Architectural Consultant and return in a month to present final ordinance details for consideration. BACKGROUND: On May 6, 2008, the City Council amended the P1aiu1ilg Commission work program to vlclude a limited review of the R-1 Ordinance regarding the allowed ratio of the second floor building area compared to the first floor building area. The intent is to allow greater design flexibility to property owners. The Council directed the P1aiuling Commission to present recommendations on ordinance options to the City Council.by October 2008. On July 8, 2008, the Planning Commission reviewed the proposed Rl Ordinance amendment. The Commission directed staff to provide a focused ordinance frainev~~ork with specific list of principles and guidelines that will address Cupertilo's residential development needs. On September 9, 2008, the Planning Commission reviewed the proposed design review framework, and recommended denial to the City Council, citing the need for a more comprehensive design review process for two story homes to address overall massing, design and review process. DISCUSSION: The currently 45% second story floor area ratio has resulted in a "wedding cake" style of architecture that is slowing becoming the predominate style of new two-story homes or additions n many neighborhoods. By creating a process that allows homeowners to increase the second floor ratio, ne~v architectural opportunities become available. ' Staff believes that achieving architectural diversity does not require increasing or decreasilg the total allowed building area on an R1 lot or changing the milimum setback requirements. Through appropriate design review and specific enhanced design principles, homes may be allowed to exceed the 45% second floor area limit n exchange for higher design quality and broader range of architecture. Iii addition, the proposed process is voluntary, only applicable to those wishing to increase their second floor area above 45%. Homes that are designed to meet the existing R1 Ordnance would only be subject to the current R1 Ordinance standards. Please refer to the attached August 26, 2008 Planning Commission staff report for the detailed staff proposal. 13-2 n4CA-2008-03 - R1 Ordinance October 21, 2008 Page 3 Planning Commission Recommendation Planning Commission voted 4-1 (Miller voting no) to not recommend the proposed approach to deal with the 2nd floor to 1St i7oor ratio. The Commission believes that the concern for design diversity and functionality are better addressed by evaluating a more comprehensive design review :process for t~vo story homes including consideration of the allowable overall floor are ratio and the 2nd floor to 1St floor ratio. Primary concerns of the Planning Commission are as follows: ^ Massive and visually intrusive Homes will result fr'o112 111C1'eaS111g tJ1e 21~ floor ratio to potentially 100% of tJ2e 1St floor (especially o~z small lots). . ^ Not enough process or detail specifies to achieve t12e desired architectural quality and diversity. ^ Evaluation should also include the total floor area ratio afid a more comprehensive design review process. ^ Clear expectation of the design requirements and review time should l7e provided. Please refer to the attached September 9, :2008 and July 8, 2008, Planning Commission meeting minutes for the detailed discussion. Staff Comments/Recommendation Massive and visually intrusive homes: In most cases, having 100% 2nd floor area to 1St floor area ratio is impractical and mathematically challengilg due to the physical constraints resulting from typical lot sizes, minimum setbacks, and functional living space requirements on the 1St floor. Those lots that can accommodate bet~veen 75-100% 2nd floor to 1St floor ratio would have to substantially reduce their building; footprints to not exceed the total floor area of 45% (see illustration # below). Conseq~~ently, residences ~Tould be oriented further away from adjacent properties, creating more outdoor space/buffer and lessen visual intrusions. Tlne illustrations below are example building footprnts and setbacks on two typical Cupertino lot sizes (5,000 and 7,000 squarE~ feet) intended to compare buildung massing and relationship to adjoining properties between a typical 45% 2nd floor to a 100% 21zd floor. 13-3 MCA-2008-03 - R 1 Ordinance October 21, 2008 Page 4 ~, ~ +- ~ r ~~ x' ~Nt ~I Y,I E 1 - ' ~ I I i I ' I I I - -~ ' -.-._ ~ ~ ~Fd~r j--- -r'---:- ._ _..I-_------ -~-- - I sf~r -~- - 1 I ~~ i I ~ I i i I I I 1 I I 1 I Fk+•' ~ I i -~ ~ - - -i i ~ f~r~luj~ - uu>f -"-MlhiiHCitl ~~5 --. f?~k Sw W.~::.ARt 4 tits'} ~c'Fta;ePryC'~ _..f ~~T ~''~ ,tea f5 ~-{ ~~ ~ *- ~ ,, u., ~~ ~~ ~ ~ '~'I N_,+I ~x~ HI ~1 '~ I~ i I 1 ~ j i , -- - I I-- yc~r r7 _ _ I I tSPCc7 .i 1 I I I I W I ~ n. ~ `•, ! j ~ '" i I I I I f 1 -_ _ _._ _-'_~_-..~_ .__...I,._ 6c Fes' - - ~ - -- - - - - ~ I 2=`Getr i -~---1---- 1 i I I I ' I i 1 I _ PrRO~.'Y _ I I ~ I z ~ I ~,I),~ PRtfLRFYUNE _~-~K~IN~uH S,~T f-- ~'if~k s`"~~ "3~s FZ ~ FRR~ C+oo t l~~~ a"`r - rs--> Lot Size: 5,000 Square Feet Lot Dimensions: 50 feet X 100 feet 13-4 MCA-2008-03 - R 1 Ordinance October 21, 2008 Paae 5 ~ ~ ~ w ~', 4: +~ ~ ..... ~ ~ F - try.

Additional process and details deeded to achieve architectu~•al diversity: The intent of the new design review process for homes exceedu1g 45% second floor to first floor building area ratio is to provide greater design flexibility. Therefore any new design standard must provide adequate flexibility to facilitate a variety of potential design concepts. The staff proposed ordinance framework includes specific design - 13-5 MCA-2008-03 - R1 Ordinance October 21, 2008 Page 6 principles and visual relief techniques. These principles and techniques are not intended to establish or dictate a specific style or mass but would rather provide assistance to applicants to understand various methods for minimizing visual mass. Please refer to the attached August 26, 2008 Planning Commission staff report for additional details on the proposed design principles and visual relief techniques. Council Option: The Council can direct additional review process or details if necessary. Additio~zal evaluation of the total floor area ratio and a more compreherzsive design review process: As mentioned previously, staff believes that achievilg architectural diversity does not require changing the maximum 45% total buildung floor area ratio. By creating a process that allows applicants to increase the second floor ratio, new architectural opportunities become available. Staff believes the proposed design principles and review requirements would offer an alternative and streaml"used process for homeowners and design professionals. Council Option: The City Council can initiate a more comprehensive residential design review process/guidelines similar to Los Gatos and Los Alto, if warranted. Other Related Minor Ordinance Changes Setback surcharge and 50% second floor exposed wall requirement Aside from the proposed design principles and techniques, staff suggests that homes exceeding the 45% second floor to first floor building area ratio would also be exempt from the second floor 10 feet setback surcharge requirement. In addition, the 50% second floor wall exposure requirement would be revised to include the proposed visual relief measures discussed in the previous section of the staff report. Other miscellaneous changes Staff is recommendung additional language clarifications be made relating gardening activities allowed in the Rl district and minor wording change to improve readability of the general Rl Ordinance. Please see attached redline ordinance XXX for additional details. 13-6 ACA-2008-03 - R 1 Ordinance October 21, 2008 Page 7 COUNCIL OPTIONS: The City Council may consider the following options: 1. Do not authorize any change to the R1 Ordinance. 2. Adopt the Planning Commission recommendation and initiate a review of the R1 Ordinance including but not limited to topics on the ratio of 2nd floor area to 1St floor area, the total 45% floor area ratio and the overall R1 design review standards/process. Note: This option will add significant time and cost to the process. The City would have 3. Adopt the staff recommended ordinance framework and direct staff to work with the City Architectural ConsulEant and return in a month to present final ordinance details for consideration.

Review the draft ordinance framework and provide comments or direction to Staff; or 2. Recommend that the City Council adopt the R-1 Ordinance amendment regarding the first floor to second flo~~r ratio requirements. BACKGROUND. On May 6, 2008, the City Council amended the Planning Commission work program to include a limited review of the R-1 Ordinance regarding the allowed ratio of the second floor building area compared to the first .1oor building area. The intent is to allow greater design flexibility to property oin-ners. The Council directed .the Planning Commission to present recommendations on ordinance options to the City Council by October 2008. Staff believes through a focused design review process, homes may be allowed to exceed the 45% second floor to first floor building area ratio thereby permitting greater architectural diversity. On July 8, 2008, the Planning Commission reviewed the proposed R1 Ordinance amendment. The Commission directed staff to provide a focused ordinance framework with specifi~~ list of principles and guidelines that will address Cupertino's residential development needs. DISCUSSION Planning Connnission Concern • The lack of the prescriptive nature oi' the new design review process. Staff Response: TITe intent of tl2e nezv design review process for homes exceeding 45% second floor to fi~•st floor building area ratio is to provide greater design flexibility. Therefore any nezu design standards must provide adequate flexibility to facilitate a variety of potential design concepts. 7~he proposed ordinance language has been revised to provide additional specificity (see attached Exhibit A). The proposed design review process is voluntary, only applicable to those wishing to increase 13-37 MCA-2008-03 - Rl Ordinance August 26, 2008 Page 2 their second floor area above 45%. Homes that are designed to meet the existing R1 Ordinance would only be subject to the current R1 Ordinance standards. ~ The new guidelines may encourage "box" style homes with uninteresting 2-story wall planes. Staff Response: Applicants will be required to have an identifiable architectural style. Specific visual relief measures or elements will be required to ensure that 2-story wall planes are broken up and treated. In addition, high quality and variation in details and materials will be required. • Currently, the R1 Exception process allows applicants to propose greater second floor areas, why create a new process. Staff Response: The current exception process does not provide any specific standards and/ or visual relief techniques to treat 2-story wall planes, or unarticulated walls to ensure architectural integrity. Also, the exception process is costly and intimidating for average property owners. Desigr2 Principles Staff believes that to facilitate greater architectural diversity does not require increasing or decreasing the total allowed building area on an R1 lot or changing the required second story setbacks. The goal is through appropriate design review and the application of enhanced design principles, homes may be allowed to exceed the 45% second floor area limit provided that that they are designed appropriately for the lot, the neighborhood, and the overall design of the structure. Staff recommends that the Director of Community Development may grant approval to a second floor to ground floor ratio greater than 45% provided that all of the followings design principles are met: 1. An identifiable architectural style shall be provided; 2. Design features, proportions and details shall be consistent with the architectural style selected; 3. Materials shall be of high quality; 4. Design with architectural integrity on all sides of the structure; 5. Visual relief shall be provided for two=story walls; 6. Ensure appropriate building mass and scale; 7. The design shall reflect symmetry, proportion and balance. The Director's decision may be appealed to the Design Review Committee or elevated to the Design Review Committee if needed. 13-38 MCA-2008-03 - Rl Ordinance August 26, 2008 Page 3 Visual Relic Techniques By allowing second floors to potentially lie larger than 45% of the ground floor to facilitate other design options, staff recommends that the following visual relief options for two story walls be added to the Ordinance: • Extended or wrap around porches • Pop outs and bay windows • Material and color changes • Wide overhangs with projecting brackets • Juliet balconies :• Window boxes and pot shelves • Landscaped trellises and lattices • Or other similar architectural features deemed to be appropriate by the Direct of Community Development Other Related Minor Ordinance Changes Homes exceeding the 45 % second floor to i'irst floor building area ratio would also be exempted from the second floor 10 feet setback surcharge requirement. In addition, the 50% second floor wall exposure requirement would be revised to include the proposed visual relief .measures discussed in the previous section of the staff report. CONCLUSION If the Planning Commission finds merit iri the proposed ordinance framework then Staff will work with the City Architectural Consultant to enhance the document with additional graphics and illustrations. T'he Planning Commission will have the opportunity to review the final draft beforE~ making its formal recommendation to the City Council.

They are intended to allow greater flexibility of architectural styles, and assist in developing good design practices and solutions. The principles apply to all new or remodeled two-story residences with second floor building areas greater than 45% compared with the first floor area. Traditional Architecture in Cupertino: The City of Cupertino has a variety of neighborhood architectural styles developed over many decades. Similar style homes, such as Ranch homes clustered throughout Cupertino, Eichler homes in the Fairgrove neighborhood, and the Monta Vista bungalows, were often built in relatively large groupings. Despite the diversity between these styles, they are small in scale and relatively informal. Problem Statement: One recent trend in new or remodeled homes is the demand for significantly larger than older existing homes. Because of the current 45% second story floor area ratio requirement in the Single-Family Residential Ordinance, a "wedding cake" style of architecture is slowly becoming the predominate style for new or remodeled two-story homes. However, through appropriate focused design review, homes may be allowed to exceed the 45% second floor to first floor building area ratio thereby permitting greater design flexibility. Design Review Process: To provide greater flexibility of design, an applicant may increase their second floor area and second floor wall exposure by applying additional design principles and by participating in additional architectural review. The Director of Community Development may grant approval of these projects if the following design principles are met: Design Principles: 1. An identifiable architectural style shall be provided; 2. Design features, proportions and details shall be consistent with the architectural style selected; 3. Materials shall be of high quality; 4. Design with architectural integrity on all sides of the structure; 5. Visual relief shall be provided for two-story walls. 6. Ensure appropriate building mass and scale; 7. The design shall reflect symmetry, proportion and balance. Visual Relief Techniques: Apply visual relief options for two story walls.

The Council direction limited the amendment to only consider if the current second floor to first floor ratio should be adjusted. The Council directed that this review would not consider changung the setback requirements or the allowable overall building floor area ratio. The concern is i:hat the 45% second story to first floor ratio requirement inadvertently encourages homeowners to increase the size of the first floor to ensure the second floor proportion is large enough to accommodate the desired number of bedrooms. Also, the current second floor to ground floor ratio results lln a repetitive style of "wedding cake" architecture making it difficult to design other traditional styles of architecture such as ;'Victorian" or "Queen Anne." The following sections of the staff report will discussion ordinance options to adjust the allowed second to ground floor ratio to allow greater architectural diversity. A citywide postcard notice of the pubic hearing was mailed out to Cupertino residents inviting them to participate i1 the discussion (see attached). DISCUSSION Existing Ordinance The existing Rl Ordinance was updated i:n January 2005. One of the major changes was to increase the 2nd floor to ground flag ratio from 35% to 45%. The intent was to allow enough space on the 2nd story to accommodate three bedrooms jvhile controlling the overall mass and scale. Since the 2005 ordunance amendment, very fe~v p~.zl~~ic A2CA-L. ,d-03 -R1 ordin.....~e 7uly 8, X008 Pale 2 concerns have been expressed about the allowable second floor building space. Rather, there has Ueen an increase of concerns regarding the limitation of architectural flexibility due to the second floor to ground floor ratio. V1~eddi~ig Ca~.e Style of Architecture The current ~5% second story floor area ratio has resulted in a "wedding cake" style of arcltecture that is slowing becoming the predominate style of nets t<aTo-story homes or additions in many neighborhoods. Although exterior design elements, such as corbels, ~vailscotng, and tvndow treatments, are provided to suggest an architectural style, the overall "~~Teddng cake" style is the same from house to house. The images below are examples of the existing Rl Ordnance "tveddilg cake" style architecture: Many residents attempt to personalize their home with design elements representing traditional architecture, however the fnal result is greatly limited by the existing second floor area restriction. This is especially the case on smaller lots Colder 6,000 square feet where the width of the lot is already restricts desib 1 options. 13-42 - ., ~, ,;;, ~.._ -~, S Y f~~ Y _ ~ _ d ~}~ ia~y a 1 r l~ .. MCA-~,,~8-03 - Rl ordina,,ce July 8, 2008 Page 3 Traditional Architecture Traditional architecture, such as Victorian., Queen Anne, Farmhouse, Colonial Revival, Italian Renaissance, typically have the majority of the second story walls aligned with the ground floor walls. Second story walls may even cantilever over portions of the ground floor wall to emphasize a certain architectural element or material change. What is important to the traditional architectural is the attention and emphasis given to quality architectural treatments and exterior embellislunents to help visually minimize what would otherwise be unarticulated walls or boxy forms. The following are some styles of architecture that may be difficult to design under the current Rl Ordinance: When Desi~z Reo lations Are Not Applied to Two-Sfo~y Homes Two-story "box" forms can be articulated :n a tvay that muiirrtizes the mass. However, unregulated t<aTo-story homes are often sterile in design and visually imposing. Without design review, attempts to mu~unize the mass and scale (as seen u1 the following image) may not always be appropriate, and may not always aclueve the intended goal. 13-43 MCA-2w8-03-Ri ordina~~ce July 8, ?008 Pase ~ Example Design Guidelines From Otlzer Communities The neighboring communities of Los Gatos and Los Altos have accommodated greater architectural variety, while meeting the community's privacy and compatibility needs by requiring a higher level of architectural integrity in their projects. Excessive mass of a residence is not determined by the second story to first story FAR, but by the perception that the size and mass of the 1louse is too large for the size of the property. The goal is to have the home designed to fit the lot, and then apply elements that assist in reducing the perception of bulk. The City of Los Altos includes the following list of ways to reduce the perception of bulk in their residential design guidelines. They are sLUnmarized below: • Use of more than one material on an elevation is appropriate to break up the vertical mass of the house. Sometimes an accent material such as a low horizontal band of brick or stone with stucco or wood siding. • Soften the elevation jvith the use of architectural elements (porches, bays, overhangs, trellises), and detail (molding, trip, brackets, etc.) • Use color changes to help visually break up the elevation. For example, painting the triangular area i1 a gable end one color and using a shade (or color) lighter or darker below. • Provide some variation in large expanses of wall and roof planes. For example, cantilever the second floor over the first floor. • Use horizontal elements to soften vertical ones in an elevation. A change of direction u1 sidu1g or addutg moldings i1 stucco can achieve this. • In some cases, a simplification of shapes and materials will reduce bulk. For example, too many different materials and changes in types of Svildo~vs add complexity of the facade. • Minimize use of tall or twa-story-high design elements. Tlis ~a~ould include t~vo-story entry ~aTays, turrets, ect. • Use visually heavy materials sparingly, particularly on t~vo story designs. Use stone or brick as an accent material or wailscot on an elevation. ~s-aa Example of aNon-Regulated Two-Story Residence. 1\2CA-2~~8-03 - Rl ordinance 7uly 8, 2008 Paoe ~ • Choose landscape materials to help soften the appearance of bulk. This should not be a substitute for good design ho~~~ever. • Keep second floor exterior wall heights as low as possible. • Use roof forms that reduce bulk (lo~v to medium pitch, minimum number of hips and valleys. • Avoid massive, tall chimneys. Locate them either on an internal wall or centered on a gable end when possible. The following is some architectural tecluuques used by Tojvn of Los Gatos to provide visual relief for tcvo story walls: • Horizontal belly bands • Pop outs and bay windo~~Ts • Material and color changes • Chirruleys • Wide overhangs with projectuzg brackets • Juliet balconies • Window boxes and pot shelves • Landscaped trellises and lattices All or some of the above methods may be applied to a new or remodeled residence (see images belo~aT). MCA-2008-03 - R1 ordinance July 8, ?008 Page 6 Reco~7znzended Ordinance Solution Staff believes that achieving architectural dig=ersity does not require increasing or decreasing. the total allowed building area on aln Rl lot or changing the required second story setbacks. The goal is through appropriate design review and the application of enhanced design principles, homes may ~be allo~~~ed to exceed tlne ?5% second floor area limit provided that that they are designed appropriately for the lot, the neighborhood, and the overall designs of the structure. Staff recommends that if an applicant wishes to increase the second story FAR above 45%, then a discretionary staff level design revie~~T be incorporated into the process with notification to the adjacent neighbors. Additional architectural principles would be upheld, while maintaining the existing goals of symmetry, proportion and balance. The Director of Co~sununity Development may grant approval to a second floor to ground floor ratio greater than 45% provided that the followings design principles and tecluniques are met: • Ensure_approUrate ardlitectural interest and compatibility with neighborhood desi~~-n theme and character. ~ Add visual interest to the elevation with the use of architectural elements (i.e., porches, bays, overhangs, trellises, moldings, trip, jvood sidungs, brackets or metal work). 13-46 MCA-2008-03 = Rl ordinance July 8, 2008 Pave 7 ~' • Ensure appropriate building mass rind scale. ~ Avoid monumental scaled forms (e.g. towers, turrets and tall entry features) that contrast with the neighborhood architectural forms. ~ Avoid eave lines and roof ridges that are substantially taller than the ' adjacent houses. ~ Use more than one material on an elevation to break up the vertical mass of the house. ~ Keep second floor exterior ~vall heights as low as possible. ~ Use more than one material on an elevation to break up the vertical mass (i.e, wainscot, wood siding, belly bands). ~ Use visually heavy material; sparingly (balustrades or stone on second floor). ~ At least 25% of all two story wall planes should be treated with architectural features to provide visual relief and architectural interest (include but not be limited to stone, brick, alternative siding materials, balconies, porch elements, long roof eaves, window boxes, pot shelves; cantilever features, trellises, corbels, trims, metal work, other features deemed appropriate). ~ Use landscape materials to Delp soften the appeara~.lce of bulk. ~ Use color changes to help visually break up the elevation. • Design with architectural integrity on all sides of the structure (maintain symmetry, t?roportion and balance ~ Avoid overly complex architectural elements and/or roof features. ~ Lute up architectural featurE~s and elements both vertically and horizontally (i.e., roofs or windows).

The purpose of this handbook is not meant to promote a specific type of design nor to establish a rigid set of guidelines. Instead, it is meant to guide the homeowner, architect, developer and builder in planning and executing a successful design of new and remodeled single-family dwellings. This handbook will also serve as a guide for the City Council, Planning Commission and City staff in the design review process. Often, newly built homes have more complex plan and building forms than existing houses. This fact, along with stylistic and size issues, has reinforced perceptions of newer homes as being very different from older houses. The design policies and implementation techniques in this handbook are not meant to discourage individual designs. Rather, they set forth the implementation of the findings that must be made for design review applications, serve as a basis on which decision- making bodies may base their design-review decisions, and assist in developing consistency in the approval process from neighborhood to neighborhood across the city. The primary purpose is to guide property owners toward successful solutions to their needs and to maintain the existing positive physical qualities and character of the residential neighborhoods of Los Altos. These guidelines implement the goals and policies of the General Plan. They also identify the findings from the Los Altos Municipal Code which must 6e followed to gain approval of a project. ' Los Altos requires design review on all residential construction. The majority of design review is performed by Planning Department staff. Applications for two-story construction or unusual architectural design are heard by the Architectural and Site Control Committee (A&S), a subcommittee of the Planning Commission. The functions of the A&5 Committee are delineated in the Los Altos Municipal Code. From a historical perspective, the character of neighborhoods in Los Altos relates back to the incorporation of the city in 1952. Decisions made at that time encouraged arural-like atmosphere. Thus, Los Altos developed with spacious quarter acre lots, minimal use of curbs and gutters, extensive use of landscaping and large trees, openness of front yards to the street, and the relatively low profile and height of residences. Prior to the City's incorporation, housing had developed more in continuity with surrounding communities; thus, there are areas of town that have smaller lots, and the zoning regulations distinguish between these smaller lots and larger lots in terms of setbacks, height, etc. These design guidelines, however, apply to lots of all sizes. 13-54 Residential D Sion ('rn;riPlinPc Although most of the housing stack was ~jeveloped during the 1950's and a predominant style is the "ranch", there is a vast diversity of design and style within Los Altos. Today, demands for housing are far different then they were at our incorporation. As a result, housing styles and home size have changed dramatically. Whereas, earlier there was an emphasis on "low profile", now there is a tend_ envy to "build out" a lot. Whereas, before there was an emphasis on designing from. the exterior inward now there is a tendency to design from the interior outward. At taxies this results in home designs that appear to overwhelm neighboring homes either in mass or complexity of design. To monitor such changes, the City Council first amended the zoning regulations to lower height and to establish daylight planes anti floor area to lot area ratios. After working with these new regulations fora period of time, it became evident that development standards alone are not sufficient to address ~suc:h impacts as privacy invasion and change to neighborhood character. Thus, the next step involved the adoption of requirements for design review of all new homes and remodels. These guidelines have been developed with the expectation that their use will encourage creativity that will result in a high level of residential design quality. It is recognized that guidelines do not encompass the full range of possibilities for excellence. For this reason, variation from these guidelines will be considered when compensated by a related improvement which contributes to the excellence of the project. To use these guidelines, please refer to the Table of Contents. Chapter 1 is the Introduction, and Chapter 2 explains they intent of the guidelines as well as the design review process. Chapter 3 presents inforniation on how designs is viewed in relation to the design review process. Chapter 4 presents the basic philosophy of these guidelines and provides general guidance in meeting the findings required for design approval. Chapter 5 explains procedures and includes the b~-sic "do's and don'ts" for design approval. There are three appendices: Appendix A preser.~ts the goals and policies from the General Plan that are applicable to these guidelines; Appendix B is a Glossary of Terms; and Appendix C provides a basic primer on Architecttu•al Styles, and can assist you in identifying the style of your home. We wish you well on your project! ~3-55 4.0 DESIGN GUIDELINES PHILOSOPHY This chapter defines the philosophy of Los Altos with regard to how housing should develop within our neighborhoods. This chapter is general in nature and reflects the major concerns of neighborhood compatibility and site planning, including the relationship of your property to adjacent properties. The next chapter goes into greater detail regarding the do's and don'ts for all new construction and remodels. These guidelines were developed from the belief that there can be a balance between the desires of the community to achieve neighborhood compatibility in house design and individuals' rights to build their "dream home". There is a need to be sensitive in crucial areas that govern the relationship of a home to its surroundings, e.g, existing homes, public streets, open spaces, privacy invasion, etc. These guidelines are not intended to prescribe a specific style, nor to limit development to one story in height. 4.1 NEIGHBORI300D COMPATIBILITY Before starting the design process, you should understand the character of your neighborhood and the impact your project will have on the neighborhood. Not all neighborhoods have clearly defined boundaries or character. Often, the boundaries of a neighborhood are delineated by arterial streets, topography and other non-architectural features. Neighborhood character within a subdivision may be a result of private CC&R's (Conditions, Covenants, and Restrictions). These CC&R's may contain restrictions on height, size, setbacks, and other design issues. Review your title report to see if there are any CC&R's that may apply to your project, Even though enforcement of CC&R's is a private civil matter, you will need to acknowledge on your design application whether your project follows all CC&R's. When the applicant indicates that a project deviates from the CC&R's, the neighbors will be notified. Neighborhoods in our community fall into one of the following groups: consistent, diverse and transitional. Following is a discussion regarding each of these types of neighborhoods. One of the considerations for a project is the compatibility it has within the neighborhood. A project determined to be inconsistent with the neighborhood will not necessarily be denied. It may be that mitigation will be required in order for the project to be approved. CONSISTENT CHA1tACTER NEIGHBORHOODS: These neighborhoods have a similar style and character to the homes and streetscape. This does not mean that the homes are exactly alike, just that they share similar 13-56 characteristics of style, house type, setbacks, and streetscape character. l~iajor renovation or new construction projects in these neighborhoods require more design sensitivity to the neighborhood than other neighborhood types when they depart from the neighborhood character. • In consistent character neighborhoods, good neighbor design has design elements, material, and scale found within the neighborhood and sizes that are not significantly larger than other homes in the neighborhood. The emphasis should be on designs that "fit in" and lessen abrupt changes. • APP~~aI of an inconsistent design will require mitigating design measures to lessen the neighborhood impact iViitigation may include change in size, increased setbacks, large trees or other landscape materials for screening and other changes in design to reduce impacts. The; goal of mitigation is to soften the differences between the new construction and the existing homes. story entry ~ r~9e ~eaa/~ ~L11G , •, Less Oasirable Desira6lw Consistent Character Neighborhood: Remodels & Additions DIVERSE C~~C'TER NEIGHBORHCIODS: In contrast, diverse character neighborhoo~js contain a variety of architectural styles and may have a varying streetscape as well. Tlus can result from homes which were built in different eras or by.individual homeowner/developers, or be a result of a neighborhood in transition. 13-57 consistent Setbacks w~~ais-en[ r+eignts~Massing s t r e e t Diverse House Types & Setbacks ridge height ._ _ eaves fir1~ m m '- ~ - - mm Ranch Bungalow Spanish Diverse Styles and/or Sizes • In a diverse character neighborhood, good neighbor design. has its own design integrity while incorporating some design elements and materials found in the neighborhood. • Mitigation for items such as size and bulk may be used for some designs depending on the relationship of a home to its neighbors. T~NSTI'IONAL CIIAR~CTER NEIGHBORHOODS: Transitional character neighborhoods are those that are in the process of changing their character and identity. Major changes include two-story additions in a one-story neighborhood, large homes in a neighborhood of small homes, and many upgraded homes in a neighborhood of older, smaller designs. • In a transitional character neighborhood, a good neighbor design reduces the abrupt changes that result from juxtaposing radically different designs or sizes of structures; proposed projects should not set the extreme and should be designed to soften the transition. Significant deviations could be cause for mitigation. turret ~^;^~. 3 Car c}a.r~e. ta.U. chi.mttLyS rt~ ' ~'"J "' tortes _ _„~eave lute ~ --- , Not Desirable Desirable Transitional Character Neighborhood: Remodels & Additions 4.2 SITE PIAIITNING Integration of your home with the site is an important aspect to good design.

Part of this perception is due to the size an~j mass of the house compared to the size of the property. Usually, the perception is that the home is too big for the lot A home should be designed to fit the lot and surroundings and with internal design integrity. Then, the elements you have chosen must lend themselves to reducing the perception of bulk - There are many ways to reduce the perception of bulk Some of these include: • Use of more than one material. on an elevation is appropriate to break up the vertical mass of the house. Sometimes an accent material such as a low horizontal band of brick or stone with stu~~co or wood siding above can be appropriate. However, too many elements can add to the appearance of bulk; good design must achieve balance. • Soften the elevation with the use of architectural elements (porches, bays, overhangs, trellises) and detail (moldings, trim, brackets, etc.). Be careful not to overdo, though. • Use color changes to help visually break up the elevation. For example, painting the triangle area in a gable end one color and using a shade (or color) lighter or darker below. • Provide some variation in. large expanses of wall and roof planes. For example, cantilever the second floor ov~:r the fu•st floor. 13-59 • Use horizontal elements to soften vertical ones in an elevation. A change of direction in siding or adding moldings in stucco can achieve this. • In some cases, a simplification of shapes and materials will reduce bulk. For example, too many different materials and changes in types of windows add to the complexity of the facade. • Minimize use of tall or two-story-high design elements. This would include two-story entry ways, turrets, etc. • Use visually heavy materials sparingly, particularly on two-story designs. Use stone or brick as an accent material or as a wainscot on an elevation. • Choose landscape materials to help soften the appearance of bulk. This should not be a substitute for good design, however. • Keep second floor exterior wall heights as low as possible. • Use roof forms that reduce bulk (low to medium pitch, minimum number of hips and valleys). • Avoid massive, tall chimneys. Locate them either on an internal wall or centered on a gable end when possible. • Design the house from the "outside-in". Houses designed from the "inside-out" rather than the reverse tend to look lumpy and lack a clear overall design. This often adds to the perception of excessive bulk • Lower the height of a iwo-story house below 27 feet maximum to mitigate other design issues. Keep in mind that overdoing anything can result in added bulk 5.5 IANDSCAPING Natural features, such as mature trees, rock outcroppings, and other landscape elements should be retained; quite often they can serve as design inspiration. • Designs should take advantage of natural features found on site. Natural features include mature trees and other landscape materials (hedges, tall shrubs), rock outcroppings, and creeks.

This diversits% is one of the features that contributes to the Toa%n's unique identity Older Victorian St3=le homes, Spanish Eclec- tic Sts=1e homes and new interpretations of Craftsman Style homes often occupy the same street front. One-story Suburban Ranch Sts-1e homes map occupy one street of a larger neighborhood while newer tv,=o-story contemporary homes may occur around the corner or don%n the street. ~sJlule this juxtaposition might seem harsh if repeated in a new community, the large amounts of mature land- scaping and the e~-olution of the Toa-n's neighborhoods over a long period of time have alloy=ed the community% to comfortably absorb this diversit5% of home sizes and styles. . Perhaps more than these mitigating factors, the self-restraint of residents and the mutual respect of one neighbor for the next has contributed to neighborhoods u%ith a great deal of visual unit5% and similarity in scale. ~fi~hile architectural sts-les often var}= considerably in any individual neighborhood, few homes stand out in marked contrast to the predominant size and bulk of their surroundings. The intent of these guidelines is to set forth some of the common sense techniques that have been employed over the years to achieve this strong sense of communit3~ 3.1 GENERAL BUILDING DESIGN PRINCIPLES The follo~z-ing principles have been used as touchstones for the development of these design guidelines for home additions and new houses. l:n the event that the specific guidelines do not clearly address a given condition, these general principles, along v%ith the Basic Design Principles on page 11 should be consulted for direc- tion. The following principles a%ill be used by the Town staff and Planning Commission/Town Council when evaluating projects, and when considering .the acceptability of unique proposals that vary from the specific guidelines. ^ 5elected architectural styles shall be compatible with the surrounding neighborhood. ^ Design features, proportions and details shall be con- sistent v~=ith the architectural style selected. ^ Materials and design details shall be suitable to the neighborhood and consistently used on all sides of the house and any accessory structures. ^ Garages shall be subservient to entries and ground floor living spaces. ^ The use of renew=able energy resources for heating, cooling and lighting should be maX;,~r,;~ed. ® Projects should be designed to conserve energy and water. NEON HOMES SHOULD BE ADAPTED TO THE SCALE OF THE SURROUNDING NEIGHBORHOOD ~X~hile some larger nea% homes map be acceptable in established neighborhoods, they u=ill be e~-pected to be designed to mitigate Their ~~isual size and bulk.

' 3.2.2 Df~sign for architectural integrity • In general, it is best to select a clear and distinctive arcli- tectural style rather than utilizing generic design elements or mi~:ing elements from different architectural st5,les. • BLilding massing, roof pitches, materials, window t<pes an~j proportions, design features (e.g., roof dormers), and other architectural features should be consistent a7th the traditions of the selected stile. • Carry wall materials, window tipes and architectural details around all sides of the house.

Unless the architectural style selected clearly sup- ports substantial complexity, generally keep building mass- ing and roof forms simple as is the norm for traditional architecture. • Avoid complex second floor plans and roof forms if that is not the norm for the neighborhood. 3.3.2 Height and bulk at front and side setbacks • Two story houses map not be appropriate for every neigh- borhood. For neighborhoods dominated by one story homes, an effort should be made to limit the house to one story in height or to accommodate second floor space v7thin the roof form as is common in the Craftsman Style. • ~~Uhen utilizing a cellar or extended foundation wall, avoid setting the first floor height at an elevation above grade that a=ould be significantly different than those of the adjacent houses. Cellar s are defined as an enclosed area that does nat exte~zd more tha~z 4feetabove the existirzgorfz~zishedgrade, and are zzot cou~zted in the Floor Az-ea Ratio calculations, by Tow~z Councilpolicy.

In the spirit of that intent, applications with cellar space will be carefully evaluated to ensure that substantial e~o~~s have been made to reduce visible mass to e~zsure compatibility with the site's immediate neighborhood. For text of the Cellar Policy, see Appendix C. Avoid eave lines and roof ridge lines d7at are substantially taller than the adjacent houses. Give special attention to adapting to the height and massing of adjacent homes.

Unless the architectural sty*le traditionally has the second floor front wall at or near the first floor mall, set the second floor back from the front facade a m;n;mum of 5 feet • The design of t~~o story homes constructed adjacent to one story houses should include techniques to min;m;>.e their visual impact and provide transitions in scale. Some techniques include: - Step down to one story elements near the side set- backs - Prop-ide substantial side setbacks for the entire house - Provide substantial second floor side setbacks - Use hip roofs at the sides rather than gables • Avoid monumental scaled forms (e.g, towers or turrets) that contrast vrith the neighborhood architectural forms. • Avoid bay windoaTs and other features that compete arith the entry as the home's focal point. • Avoid the use of too many active building forms added to the mass of the building An e~:cessive use of roof forms is a common problem. 3.3.3 Provide visual relief for tvvo story walls Some techniques include: • Belly bands (see photo below left) • Pop outs and bay azndows • ?~Zaterial and color changes • Chmneys • ~~Tide overhangs with projecting brackets • Juliet balconies (see photo below left) • ~~vZdow bogies and pot shels-es • Landscaped trellises and lattices This Craftsman Style house includes several features to mitigate the visual height of the side wal! 13-67 Residential Design Guidelines 24 Public Review Draft February 1.2008 Avoid too many building elements competing for attention Avoid too many roof forms that overly complicate the design Other t,vo story wall mitigation techniques Town of Los Gatos BUILDING DESIGN 3 3.4 GARAGES 3.4.1 Limit the prominence of garages Avoid designs that allow the garage to donvnate the street facade. • Limit the garage width to a maximum of 50 percent of the total facade width. • Set garages back from the front facade. Limiting the width of garages and setting them back from the front facade can minimize their visual impact • Recess garage doors as much as possible from the garage facade. • Consider adding trellises with landscaping o~Ter garage doors to soften their ~7sual appearance. • Integrate the garage into the house forms in a manner that de-emphasizes the garage doors. -~ ~j=~~ _~~ - - - - ~ ~ _ - . ~. ~~ _ "~' r t ~+~~. .~ ; '~ - ~ - _~ ,,,F - - -,~- Divided garage opening with high quality wood doors and a roof form tivith dormer integrated into the main house helps minimize the visual impact of this garage 13 - ss Residential Design Guidelines Public Review Draft February 1, 2008 25 Avoid designs that allow the garage io dominate the street facade (Ike this one does Recess garage doors from the facade as much as possible Use windows and landscaped trellises over garage doors to soften their appearance BUILDING DESIGN 3 Town of Los Gatos 3.4.2 IVlinimize the visual impact of larger garages Three car garages may not be appropriate in most neighborhoods. ~~ilhere larger garages are customary and appropriate, steps should still be ta~en to min;m».e their ~risual impact on the house and streetscap~.

It should be risible from the street. Pro.~7de a separate wall-way from the sidewalk to the entry if that is the common pattern for adjacent and nearby homes. Avoid using the drip>ea~ay as the u~alb-a~ay to the entry unless that is the norm for the neighborhood. In cases vThere the driveway is used, consider the use of modular pacers or decorative banding. 3.6.2 Design hone entries with sensitivity to the architectural style • Trost architectural styles ha~-e a distinctively unique entry type. Avoid using an entry type that is not part of the st}•le. For example, avoid using projecting entries, especially those with an eave line higher than the first floor roof, for Ranch Style houses or in Rands StS~le neighborhoods. 3.6.3 Design entries with sensitivity to the surrounding neighborhood • Avoid large and formal entries unless that is the norm for nearby houses. It is often best to start the design consid- eration arith an entry t3Tpe (e.g., projecting or under eave porch) that is similar to nearby homes. • Houses on corner lots should consider using porches that wrap around from the front to the side elevation, as shown below This can assist in reducing the ~7sua1 height of taller side v~alls, and in enlivening the side street frontage. .

BUILDING DESIGN 3 Town of Los Gatos 3.7 N~INDOWS 3.7.1 Arrange windows in patterns and groupings consistent with the architectural style and surrounding nE~ighborhood • Mang architectural sty=les hat=e inditidual windows that are grouped into patterns of two, three or more windows. Be conscious of this fact, and organize the uindoa=s to comple- ment the style. 3.7.2 Match window types and proportions to the architectural style and to the surrounding nE~ighborhood • Select ~;~indow ts~pes to complement the stile of the house. Each architectural style generally has one or two window t3-yes that are traditional to the stile. Double hung windows, for e~:an~ple, are common features of Victorian and Crafts- . man Sts=les while casement windows are seen frequently in I\~i.ssion and Spanish Eclectic styles. Most architectural sty=les feature aindoaTs that hat=e either vertical or square proportions. Avoid horizontal window proportions unless the sty=le (e.g.,1\Sodern or Ranch Sty-1e) is clearly supportive of that shape. Horizontal groupings of~ vertical and square windows are one means of providing z7sual balance to a facade design. Limit the number of different w=indow types and propor- tions to enhance the visual uniti of the house design. For second floor additions to existing homes, matd~ the Windows on the original first floor. Match the size and shape of vindoty shutters to the shape ar.d size of the uindoa~s. Shutters that are large enough to corer the windows, if closed, should be the goal. Hinges oii shutters to allow their closure are desirable. Avoid very ns.rrow shutters that are clearly not wide enough to corer the window opening. 3.7.3 Match window Enaterials to the architectural style and to the surrounding neighborhood • good a-indows are common in Los Gatos. good is still the desired choice for sty=les that traditionally used a=ood. However, today there are some window materials, such as vinyl clad a=ood windows that are not noticeably different from wood at a short distance. They map be used if their visual appearance matches wood. • Generally; avoid metal windows. They may be considered acceptable for a Modern Sty=le house, but uTould be strongly discouraged for all other styles. 13 - 73 30 Residential Design Guidelines Public Review Draft February 1, 2008 Group windows in a manner that is traditional for the architectural style Most architectural sty"!es have vertically proportioned ~vindotvs t~ndows with some depth from the frame to the glass are desirable Tosvn of Los Gatos BUILDING DESIGN 3 3.7.4 Design the windows with attention to matching the traditional details of the architectural style DSost architectural sty=les -except Mission, Spanish Eclectic or Modern -should have ~=ood trim around the w-indou=s. The trim width should be matched to the st3=le, but in gen- eral, should not be less than 3 1 /2 inches wide. Head trim depth should be equal to or wider than the jamb casing, but not less than one-sixth of the opening width. • Projecting window= sills and heads are strongly encouraged unless the architectural sty=lea=ould not normally have those features. • Wood true is also encouraged on stucco houses unless the window frames are recessed at least 6 inches from the out- side face of the a=all. The use of stucco covered foam trim is strongly discouraged. Divided lights (i.e., larger a~.ndovT panes broken up into smaller pieces) are common in many home styles found in Los Gatos. Use either vertical or square proportions for the smaller w~indoty elements. Be consistent in the proportions (.e., the ratio of the horizontal to the vertical dimension) of the smaller panes. Do not use snap in flat grids to simu- late di~~ded lights. Use eider true divided lights or one of the newer window systems that have dimensional muntins on both the exterior and interior of the glass along and a spacer muntin beta=een the panes of glass. Use consistently for windows on all sides of the house. 3.7.5 Special window shapes and styles should be used sparingly • Avoid Estate Home S~-Le windows (e.g., tall arched window,=s) in neighborhoods where the homes are more modest and informal in character. Bay window=s should be designed add a base element to the ground or a~di supporting brackets at the base. Sloped roofs should be used and covered with a material that snatches the roof material or with metal. Avoid using wall materials beta=een the individual windows of the bay window unless the window is large.

Although individual homes drat are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit, the potential for water contamination from copper is of concern to all Bay Area com- munities. The major uses of arcltectural cop- per in residential construction are roofs, gutters, and copper-treated composite shingles. Town of Los Gatos 3.8 M;ATERlALS 3.8.1 Use high quality materials • Use materials and mixes of materials that are consistent ar:th the architectural st3%le selected. • Traditional materials, such as ~~ood~and stone, are most desirable, and strongly encouraged. Ho~Te~=er, the cost of materials and labor for many building components have led to the development of synthetic materials that are often hard to tell from the authentic ones. If any of these substitutes are selected, they must pass the test of looking like the authentic material at a distance of 3 feet if used on the first floor and 10 feet if used on the second floor. • A, oid rough textured stucco in favor of a smooth sand fvush. • C~~mposition roof shingles may be acceptable in lieu of wood shakes. However, shingles should be selected with a texture that is similar to other houses in the neighbor- hood. 3.8.2 Select materials that are sensitive to the surrounding nf~ighborhood • One way of fitting a new house into an existing neighbor- hood. -especially if the new house is bigger than many of the others around it - is to use materials drawn from the surrounding neighborhood. An all stucco house might seem out of character in an all wood neighborhood, but the predominant use of ~x~ood siding v,7th some elements of stucco can often work. Where stone accents (e.g., chim- neys) are common in a neighborhood, the use of stone at the a-all base and elsewhere can assist in making the ne~~ home seem better connected to its surroundings. • When using a mix of materials, avoid using too many materi- al:~ -two or at most three are enough. Avoid an even split of materials (i.e., SO/50)~on the facades. It is best to have one material as the dominant surface a~th the second material playing a lesser role. The use of a two-third to one-third ratio is a good place to start '5 32 Residential Design Guidelines Public Review Draft February 1, 2008 2~3 stucGO 1f3 wood Town of Los Gatos t BUILDWG DESIGN 3 3.8.3 Use traditional detailing • Treat openings in walls as though they u=ere constructed of the traditional material for the st3=1e. For example, be sure to provide substantial a=all space abo~=e arches in stucco and stone walls. Traditionally; wall space abo~=e the arch u=ould ' have been necessary to structurally span the opening, and to make the space too small is inconsistent with the archi- tectural style. • Openings in walls faced urith stone, real or s3%nthedc, should have defined lintels above the opening except in Atission or Spanish Eclectic styles. Lintels maybe stone, brick or u=ood as suits the sty=le of the house. • Treat synthetic materials as though they a=ere authentic. For e~:ample, select synthetic stone patterns that place the individual stones in a horizontal plane as they u=ould have been in a load bearing masonry wall. • Select roof materials that are consistent a=ith the traditional architectural sty=le (e.g, avoid concrete roof tiles on a Crafts- man Sts=le house.) 3.8.4 Materials changes • Make materials and color changes at inside corners rather than outside corners to,avoid a pasted on look. ~~ res ~,j Ap~~~-1 t~t6 1 sr c~[or Change »t~b¢rials Nc! al aRd colar~ ~t ou~Fd~ irtg5de comers c~rnyrs 3.9 ADDITIONS/ACCESSORY BUILDINGS/SECONDARY UNITS Follow the provisions set forth in Guideline 4.9 on page 52. i 1 `Y ~ - 4 ~'~ t~ara~e style, farm, materials f ~'.

Take care in selecting columns with an ap- propriate w=idth to height ratio for the sty=le. Eacept for a very few sty-ley, the columns should have appropriate caps a~ld bases a7th proportions typical of the style. • Pro«de a well proportioned beans bets=een the column caps acid the roof. Size and detail the beam so that it looks like a convincing structural member. It should be risible both from inside and outside of the porch. A common problem is to make this element of the porch too small or to face it with a material (e.g., siding) that a=ould not carry the weight abo~=e if it v,-ere structural. For most architectural styles, molding and trim will di~7de the beam vertically into three n-.ajor elements of varying height. ' Railings should generally be constructed of a=ood unless the specific architectural stele allows for metal or stone. Pro«de both top and bottom rails a7th the bottom rail raised above tl-.e porch floor level. ' ~l_rtical balusters should be appropriate to the architectural style.

For longer railings, intermediate posts Frith caps ar.d bases should be used to break the railing into smaller in.rements. 3.10.3 Brackets Brackets at roof overhangs, balconies and bay window=s should be designed to extend to fascia/balcony edge/pro- jectingbay front or slightly beyond.

BACKGROUND: On Tuesday May 6, 2008, the City Council amended the Planning Commission work program to include a review of the R-1 Ordinance first floor to second floor ratio requirement. The Council directed that the Planning Commission wrap up your work in September and present the recommendation to the City Council in October 2008. ' DISCUSSION: The Council direction limited the amendment to considering if the second floor to first floor ratio should be changed. The Commission is not authorized to evaluate changing second story setbacks or other elements of the ordina~lce such as the overall floor area ratio. Council members voiced concern that the 45 % second floor to first floor ratio inadvertently encourages hoineo~vners to increase the size of the first floor to ensure the second floor proportion is large enough to accommodate the desired number of bedrooms. Also, concern was expressed that the current formula results in a repetitive stylf~ of "wedding cake" architecture. For example a "Victorian" or "Queen Anne" style of architecture is difficult to design with the current rule. Staff anticipates that the Conunission will need to address the amount of exposed second floor wall plane as this rule directly relates to the issue of potentially allowing the first and second floor walls to align. The Coirunission swill need to assess if some alternate method of breaking up the wall plane should be considered such pis awning or trellis elements. Finally, the Coi7unission may need to consider alternate r~:view procedures for applicants taking advantage of any amendments. Staff will send out achy-wide mailer and attempt to provide articles in the Cupertino Scene and on the web site to keep the public informed of this review. Staff anticipates the item will be ready for the Planting Commission in July 2008. In.the meantime staff will evaluate if this change will potentially delay any other jvork program items. ,~ SubmifiEed by: Steve Piasecki, Director of Community Developme~ 13-81 Exhibit B CITY OF CUPERTINO 10300 Torre Avenue, Cupertino, California 95014 DEPARTMENT OF COMMUNITY DEVELOPMENT REPORT FORM Application: MCA-2008-03 Agenda Date: July 8, 2008 Applicant: City of Cupertino Property Owner: Various Property Location: citywide ' Item Summary: Discussion of the R-1 Ordinance first floor to second floor ratio requirements RECOMMENDATION Recommend that the City Council adopt the R-1 Ordinance amendment regarding the first floor to second floor ratio requirements BACKGROUND On May 6, 2008, the City Council amended the Planning Commission t~vork program to include a limited review of the R-1 Ordinance regarding the allowed ratio of the second floor building area compared to the first floor building area. first floor to second floor ratio requirement. The Council directed the Planning Commission to present recommendations on ordinance options to the City Council by October 2008. The Council direction limited the amendment to only consider if the current second floor to. first floor ratio should be adjusted. The Council directed that this review would not consider changing the setback requirements or the allowable overall building floor area ratio. The concern is that the 45% second story to first floor ratio requirement inadvertently encourages homeowners to increase the size of the first floor to ensure the second floor proportion is large enough to accommodate the desired number of bedrooms. Also, the current second floor to ground floor ratio results in a repetitive style of "wedding cake" architecture making it difficult to design other traditional styles of architecture such as "Victorian" or "Queen Anne." The following sections of the staff report will discussion ordinance options to adjust the allowed second to ground floor ratio to allow greater architectural diversity. A citywide postcard notice of the pubic hearing was mailed out to Cupertino residents inviting them to participate in the discussion (see attached). DISCUSSION Existing Ordinance The existing Rl Ordinance was updated in January 2005. One of the major changes vas to increase the 2nd floor to ground floor ratio from 35% to 45%. The intent was to allow enough space on the 2nd story to accommodate three bedrooms while controlling the overall mass and scale. Since the 2005 ordinance amendment, very few pgtl~~c MCA-2008-03 - R1 ordinance July 8, 2008 Paae 2 concerns have been expressed about the allowable second floor building space. Rather, there has been an increase of concerns regarding the limitation of architectural flexibility due to the second floor to ground floor ratio. Weddi~lg Cake Style of Architecture The current 45% second story floor area r<<tio has resulted in a "wedding cake" style of architecture that is slowing becoming the predominate style of new two-story homes or additions in many neighborhoods. Altr~ough exterior design elements, such as corbels, wainscoting, and window treatmE~nts, are provided to suggest an architectural style, the overall "wedding cake" style is the same from house to house. The images below are examples of the existing R1 Ordinance "wedding cake" style architecture: Many residents attempt to personalize their home with design elements representing traditional architecture, however the final result is greatly limited by the existing second floor area restriction. This is es~~ecially the case on smaller lots under 6,000 square feet where the width of the lot is already restricts design options. 13-83 MCA-2008-03 - Rl ordinance July 8, 2008 Page 3 Traditional Architecture Traditional architecture, such as Victorian, Queen Anne, Farmhouse, Colonial Revival, Italian Renaissance, typically have the majority of the second story walls aligned with the ground floor walls. Second story walls may even cantilever over portions of the ground floor wall to emphasize a certain architectural element or material change. What is important to the traditional architectural is the attention and emphasis given to quality architectural treatments and exterior embellishments to help visually minimize what would otherwise be unarticulated walls or boxy forms. The following are some .styles of architecture that may be difficult to design under the current R1 Ordinance: When Design Regulations Are Not Applied to Two-Stogy Homes Two-story "box" forms can be articulated in a way that minimizes the mass. However, unregulated two-story homes are often sterile in design and visually imposing. Without design review, attempts to minimize the mass and scale (as seen in the following image) may not always be appropriate, and may not always achieve the intended goal. 13-84 MCA-2008-03-R1 ordinance July 8, 2008 Page 4 Example Desig~t Guidelines From Other Communities The neighboring communities of Los Gatos and Los Altos have accommodated greater architectural variety, while meeting the c~~mmunity's privacy and compatibility needs by requiring a higher level of architectural: integrity in their projects. Excessive mass of a residence is not determined by the second story to first story FAR, but by the perception that the size and mass of the house is too large for the size of the property. The goal is to have the home designed to l=it the lot, and then apply elements that assist in reducing the perception of bulk. The City of Los Altos uzcludes the folloti~ing list of ways to reduce the perception of bulk in their residential design guidelines. They are summarized below: • Use of more than one material on an elevation is appropriate to break up the vertical mass of the house. SorYietimes an accent material such as a lo~v horizontal band of brick or stone with stucco or wood sidu1g. • Soften the elevation with the use of architectural elements (porches, bays, overhangs, trellises), and detail (molding, trim, brackets, etc.) • Use color changes to help visuz~lly break up the elevation. For example, painting the triangular area u1 a gable end one color and using a shade (or color) lighter or darker below. • Provide some variation in larger expanses of wall and roof planes. For example, cantilever the second floo r over the first floor. • Use horizontal elements to soften vertical ones in an elevation. A change of direction in siding or adding moldings in stucco can achieve this. • In some cases, a simplification of shapes and materials will reduce bulk. For example, too many different materials and changes u1 types of windows add complexity of the facade. • Minimize use of tall or two-story-high design elements. This would include two-story entry ways, turrets, ect. • Use visually heavy materials sparingly, particularly on two story designs. Use stone or brick as an accent material or Svaulscot on an elevation. ~ s - as Example of aNon-Regulated Two-Story Residence. MCA-2008-03 - Rl ordinance July 8, 2008 Page 5 • Choose landscape materials to help soften the appearance of bulk. This should not be a substitute for good design however. • Keep second floor exterior wall heights as low as possible. • Use roof forms that reduce bulk (lo~v to medium pitch, minimum number of hips and valleys. • Avoid massive, tall chimneys. Locate them either on an internal wall or centered on a gable end when possible. The following is some architectural tecluiiques used by Town of Los Gatos to provide visual relief for two story walls: • Horizontal belly bands • Pop outs and bay windows • Material and color changes • Chirruleys • Wide overhangs with projecting brackets • Juliet balconies ~ Window boxes and pot shelves . • Landscaped trellises and lattices All or some of the above methods may be applied to a new or remodeled residence (see images below). _~ ~ -. MCA-2008-03 - Rl ordinance July 8, 2008 Page 6 ~..... Recommended Ordi~zance Solution Staff believes that achieving architectural diversity does not require increasing or decreasing the total allowed buildung axea on an R1 lot or changing the required second story setbacks. The goal is tlu~ough appropriate design review and the application of enhanced design principle;~, homes may ~be allowed to exceed the 45% second floor area limit provided that that: they are designed appropriately for the lot, the neighborhood, and the overall design of the structure. Staff recommends that if an applicant wi:>hes to increase the second story FAR above 45%, then a discretionary staff level design review be incorporated into the process with notification to the adjacent neighbors. Additional architectural principles would be upheld, while maintaining the existing goals of symmetry, proportion and balance. The Director of Community Development may grant approval to a second floor to ground floor ratio greater than 45% provided that the followings design principles and techniques are met: • Ensure appropriate architectural u _terest and compatibility with neighborhood design theme and character. ~ Add visual interest to the elE~vation with the use of architectural elements (i.e., porches, bays, overhangs, trellises, moldings, trim, wood sidings, brackets or metal work). 13-87 MCA-2008-03 - Rl ordinance July 8, 2008 Page 7 • Ensure appropriate building mass and scale. ~ Avoid monumental scaled forms (e.g. towers, turrets and tall entry features) that contrast with the neighborhood architectural forms. ~ Avoid eave lines and roof ridges that are substantially taller than the adjacent houses. ~ Use more than one material on an elevation to break up the vertical mass of the house. ~ Keep second floor exterior wall heights as low as possible. ~ Use more than one material on an elevation to break up the vertical mass (i.e, wainscot, wood siding, belly bands). ~ Use visually heavy materials sparingly (balustrades or stone on second floor). . ~ At least 25% of all two story wall planes should be treated with architectural features to provide visual relief and architectural interest (include but not be limited to stone, brick, alternative siding materials, balconies, porch elements, long roof eaves, window boxes, pot shelves, cantilever features, trellises, corbels, trims, metal work, other features deemed appropriate). ~ Use landscape materials to help soften the appearance of bulk. ~ Use color changes to help visually break up the elevation. • Design with architectural ulteerity on all sides of the structure (maintain symmetryproportion and balance). ~ Avoid overly complex architectural elements and/or roof features. ~ Line up architectural features and elements both vertically and horizontally (i.e., roofs or windows).

New construction shall not be disproportionately larger than, or out of scale with, the neighborhood pattern in terms of building forms, roof pitches, eave heights, ridge heights, and entry feature heights; b. The design shall use vaulted ceilings rather than high exterior walls to achieve higher volume interior spaces; c. There shall not be a three-car wide driveway curb cut. d. No more than fifty percent of the front elevation of a house should consist of garage area. e. Long, unarticulated, exposed second story walls should be avoided since it can increase the apparent mass of the second stot•y. £ The current pattern of side setback artd garage orientation in the neighborhood should be maintained. g. When possible, doors, windows and architectural elements should be aligned with one another vertically and horizontally ;end symmetrical in number, size and placement. h. Porches are encouraged. i. Living area should be closer to the sU•eet, while garages should be set back more. j. All second story roofs should have at least none-foot overhang. D. Setback-First Story. 1. Front Yard.

The purpose of this handbook is not meant to promote a specific type of design nor to establish a rigid set of guidelines. Instead, it is meant to guide the homeowner, architect, developer and builder in planning and executing a successful design of new and remodeled single-family dwellings. This handbook will also serve as a guide for the City Council, Planning Commission and City st~~ff in the design review process. Often, newly built homes have more complex plan and building forms than existing houses. This fact, along with stylistic and ;>ize issues, has reinforced perceptions of newer homes as being very different from older houses. The design policies and implementation techniques in this handbook are not meant to discourage individual designs. Rather, thE;y set forth the implementation of the findings that must be made for design review applications, serve as a basis on which decision- making bodies may base their design-review decisions, and assist in developing consistency in the approval process from neighborhood to neighborhood across the city. The primary purpose is to guide property owners toward successful solutions to their needs and to maintain the existing positive physical qualities and character of the residential neighborhoods of Los Altos. These guidelines implement the goals and policies of the General Plan. They also identify the findings from the Los Altos Municipal Code which must be followed to gain approval of a project. Los Altos requires design review on all residential construction. The majority of design review is performed by Planning Department staff. Applications for two-story construction or unusual architectural de;~ign are heard by the Architectural and Site Control Committee (A&S), a subcommittee of the Planning Commission. The functions of the A&S Committee are delineated in the: Los Altos Municipal Code. From a historical perspective, the character of neighborhoods in Los Altos relates back to the incorporation of the city in 1952. Decisions made at that time encouraged arural-like atmosphere. Thus, Los Altos developed wiith spacious quarter acre lots, minimal use of curbs and gutters, extensive use of landscaping and large trees, openness of front yards to the street, and the relatively low profile send height of residences. Prior to the City's incorporation, housing had developed more in continuity with surrounding communities; thus, there are areas of town that have smaller lots, and the zoning regulations distinguish between these smaller lots and larger lots vz terms of setbacks, height, etc. These design guidelines, however, apply to lots of all sizes;. 13-95 13esidential Design Guidelines 2 Although most of the housing stock was developed during the 1950's and a predominant style is the "ranch", there is a vast diversity of design and style within Los Altos. Today, demands for housing are far different than they were at our incorporation. As a result, housing styles and home size have changed dramatically. tiVhereas, earlier there was an emphasis on "low profile", now there is a tendency to "build out" a lot Whereas, before there was an emphasis on designing from the exterior inward now there is a tendency to design from the interior outward. At times this results in home designs that appear to overwhelm neighboring homes either in mass or complexity of design. To monitor such changes, the City Council first amended the zoning regulations to lower height and to establish daylight planes and floor area to lot area ratios. After working with these new regulations for a period of time, it became evident that development standards alone are not sufficient to address such impacts as privacy invasion and change to neighborhood character. Thus, the next step involved the adoption of requirements for design review of all new homes and remodels. These guidelines have been developed with the expectation that their use will encourage creativity that will result in a high level of residential design quality. It is recognized that guidelines do not encompass the full range of possibilities for excellence. For this reason, variation from these guidelines will be considered when compensated by a related improvement which contributes to the excellence of the project. To use these guidelines, please refer to the Table of Contents. Chapter 1 is the Introduction, and Chapter 2 explains the intent of the guidelines as well as the design review process. Chapter 3 presents information on how design is viewed in relation to the design review process. Chapter 4 presents the basic philosophy of these guidelines and provides general guidance in meeting the findings required for design approval. Chapter 5 explains procedures and includes the basic "do's and don'ts" for design approval. There are three appendices: Appendix A presents the goals and policies from the General Plan that are applicable to these guidelines; Appendix B is a Glossary of Terms; and Appendix C provides a basic primer on Architectural Styles, and can assist you in identifying the style of your home. We wish you well on your project! 13-96 4.0 DESIGN GUIDF;LINES PHIIASOPHY This chapter defines the philosophy of Los Altos with regard to how housing should develop within our neighborhoods. This chapter is general in nature and reflects the major concerns of neighborhood compatibility and site planning, including the relationship of your property to adjacent pr~~perties. The next chapter goes into greater detail regarding the do's and don'ts for all ne~v construction and remodels. These guidelines were developed from the t~elief that there can be a balance between the desires of the community to achieve neigl~iborhood compatibility in house design and individuals' rights to build their "dream horrre". There is a need to be sensitive in crucial areas that govern the relationship of a home to its surroundings, e.g, existing homes, public streets, open spaces, privacy invasion, etc. These guidelines are not intended to prescribe a specific style, nor to limit develoF~ment to one story in height. 4.1 NEIGHBORHOOD COMPATIBILTIY Before starting the design process, you should understand the character of your neighborhood and the impact your proje~~t will have on the neighborhood. Not all neighborhoods have clearly defined boundaries or character. Often, the boundaries of a neighborhood are delineated by arterial streets, topography and other non-architectural features. Neighborhood character within a subdivision may be a result of private CC&R's (Conditions, Covenants, and Restrictions). These CC&R's may contain restrictions on height, size, setbacks, and other design issuers. Review your title report to see if there are any CC&R's that may apply to your project. Even though enforcement of CC&R's is a private civil matter, you will need to acknowledge on your design application whether your project follows all CC&R's. When the applic;int indicates that a project deviates from the CC&R's, the neighbors will be notified. Neighborhoods in our community fall into one of the following groups: consistent, diverse and transitional. Following is a d:scussion regarding each of these types of neighborhoods. One of the considerations f'or a project is the compatibility it has within the neighborhood. A project determined to be inconsistent with the neighborhood will not necessarily be denied. It may be that mitigation will be required in order for the project to be approved. CONSISTENT CHARACTER NEIGHBORHOODS: These neighborhoods have a similar style and character to the homes and streetscape. This does not mean that the homes are Exactly alike, just that they share similar 13-97 characteristics of style, house type, setbacks, and streetscape character. Major renovation or new construction projects in these neighborhoods require more design sensitivity to the neighborhood than other neighborhood types when they depart from the neighborhood character. • In consistent character neighborhoods, good neighbor design has design elements, material, and scale found within the neighborhood and sizes that are not significantly larger than other homes in the neighborhood. The emphasis should be on designs that "fit in" and lessen abrupt changes. • Approval of as inconsistent design will require mitigating design measures to lessen the neighborhood impact iViitigation may include change in size, increased setbacks, large trees or other landscape materials for screening and other changes in design to reduce impacts. the goal of mitigation is to soften the differences between the new construction and the existing homes. story try ri.dgG h,ru r~,~ <<,~ Less Desirable desirable Consistent Character Neighborhood: Remodels ~ Additions DIVERSE CHARACTER NEIGHBORHOODS: In contrast, diverse character neighborhoods contain a variety of architectural styles and may have a varying streetscape as well. This can result from homes which were built in different eras or by individual homeowner/developers, or be a result of a neighborhood in transition. 13-98 consistent Setbacks ~vnsistent rtetghts/Massing i 1~ ~_ s t r e e t back l inE: Diverse House Types & Setbacks r ~ height -- _ eaaie iir~ mm " - ® -mm Ranch Bungalow Spanish Diverse Styles and/or Sizes • Ia a diverse character neighborhood, good neighbor design has its own design integrity while incorporating some design elements and materials found in the neighborhood. • Mitigation for items synch as size and bulk may be used for some designs depending on the relationship of a home to its neighbors. "IRANSTITONAL CHARACTER NEIGHBORHOODS: Transitional character neighborhoods are those that are in the process of changing their character and identity. Major changes. include two-story additions in a one-story neighborhood, large homes in a neighborhood of small homes, and many upgraded homes in a neighborhood of older, smaller designs. • In a transitional chars;cter neighborhood, a good neighbor design reduces the abrupt changes that re:;ult from juxtaposing radically different designs or sizes of structures; proposed projects should not set the extreme and should be designed to soften the transition. Significant deviations could be cause for mitigation. 3 CSr' turret ri~ ~ taU. chi.mttcy~ stonc _ _~ P.e.~ e lir>~ Not Desirable Desirable Transitional Character Neighborhood: Remodels a Additions 4.2 SITE PIANNING Integration of your home with the site is ar,; important aspect to good design.

Part of this perception is due to the size and mass of the house compared to the size of the property. Usually, the perception is that the home is too big for the lot. A home should be designed to fit the lot and surroundings and with internal design integrity. Then, the elements you have chosen must lend themselves to reducing the perception of bulk. s~ r m m~ m~ ®i ..23?Ny 6r7ry ~_ 2 SrdJ'tu~~~IIS Most Impact There are many ways to reduce the perception of bulk. Some of these include: Use of more than one material on an elevation is appropriate to break up the vertical mass of the house. Sometimes an accent material such as a low horizontal band of brick or stone with stucco or wood siding above can be appropriate. However, too many elements can add to the appearance of bulk; good design must achieve balance. • Soften the elevation with the use of architectural elements (porches, bays, overhangs, trellises) and detail (moldings, trim, brackets, etc.). Be careful not to overdo, though. • Use color changes to help visually break up the elevation. For example, painting the triangle area in a gable end one color and using a shade (or color) lighter or darker below. • Provide some variation in large expanses of wall and roof planes. For example, cantilever the second floor over the first floor. 13 - 100 • Use horizontal elements to soften vertical ones in an elevation. A change of direction in siding or adding moldings in stucco can achieve this. • In some cases, a simplific.ition of shapes and materials will reduce hulk. For example, too many different materials and changes in types of windows add to the complexity of the facade. • Minimize use of tall or two-story-high design elements. This would include two-story entry ways, turrets, etc. • Use visually heavy materials sparingly, particularly on two-story designs. Use stone or brick as an accent material or as a wainscot on an elevation. • Choose landscape materials to help soften the appearance of bulk. This should not be a substitute for good de:~ign, however. • Keep second floor exterior wall heights as Iow as possible. • Use roof forms that red~ice bulk (low to medium pitch, minimum number of hips and valleys). • Avoid massive, tall chimnE~ys. Locate them either on an internal wall or centered on a gable end when possible. • Design the house from the "outside-in". Houses designed from the "inside-out" rather than the reverse tend to look lumpy and lack a clear overall design. This often adds to the perception of excessive bulk • Lower the height of a two••story house below 27 feet maximum to mitigate other design issues. Keep in mind that overdoing anything can result in added bulk. 5.5 LANDSCAPING Natural features, such as mature trees, rocl+; outcroppings, and other landscape elements should be retained; quite often they can serve as design inspiration. • Designs should take advantage of natural features found on site. Natural features include mature tree~~ and other landscape materials (hedges, tall shrubs), rock outcroppings, and creeks.

This diversity is one of the features that contributes to the Town's unique identity: Older Victorian Style homes, Spanish Eclec- tic Style homes and new interpretations of Craftsman Stele homes often occupy the same street front. One-story Suburban Ranch Style homes may occupy one street of a larger neighborhood aThile neu=er two-story contemporary homes may occur around the corner or dourn the street. ~~Jlvle this juxtaposition might seem harsh if repeated in a new community; the large amounts of rnature land- scaping and the evolution of the Town's neighborhoods over a long period of time hay=e allowed the community to comfor~_ably absorb this diversity of home sizes and stSTles. Perhaps snore than these mitigating factors, the self-restraint of residents and the mutual respect of one neighbor for ,he nest has contributed to neighborhoods with a great deal of ~risual unity and similarit~~ in scale. ~~Jhile architectural styles often vary considerably in any indi~ridual neighborhood, few homes stand out in marked contrast to the predominant size and bulk of their scrroundings. The intent of these guidelines is to set forth some of tze common sense techniques that have been employed over the years to achieve this strong sense of community: 3.1 GENERAL BUILDING DESIGN PRINCIPLES The following principles have been used as touchstones for the development of these design guidelines for home additions and new houses. In the event that the specific guidelines do not clearly address a given condition, these general principles, along «-ith the Basic Design Principles on page 11 should be consulted for direc- tion. The following principles will be used by the To~jn staff and Planning Commission/Town Council when evaluating projects, and when considering the acceptability of unique proposals that vary from the specific guidelines. ^ Selected architectural styles shall be compatible with the surrounding neighborhood. ^ Design features, proportions and details shall be con- sistent with the architectural style selected. ^ Materials and design details shall be suitable to the neighborhood and consistently used on all sides of the house and any accessory structures. ^ Garages shall be subservient to entries acid ground floor living spaces. ^ The use of renewable energy resources for heating, cooling and lighting should be maximized.. ^ Projects should be designed to conserve energy and water. ^ Materials should be used to reduce the constunption of NEW HOMES SHOULD BE ADAPTED TO THE SCALE OF THE SURROUNDING NEIGHBORHOOD ~~Jhile some larger new homes may be acceptable in established neighborhoods, they will be expected to be designed to mitigate their visual size and bulk. Three examples are shown below nonrenewable resources and that improve :sir quality. I 13 - 105 Residential Design Guidelines Public Review Draft February 1, 2008 21 BUILDING DESIGN 3 3.2 ARCHITECTURAL STYLE 3.2.1 Select an architectural style with sensitivity to the surrounding neighborhood • StS~les with front facade eaves at the first floor level will be easier to adapt to predominantly one story neighborhoods than st5rles with taro story, unbroken front facades. • StS~les v-ith variations in the plane of the front facade wall may fit more comfortably in neighborhoods arith smaller houses or arith smaller building masses close to the street. • Avoid selecting an architectural style which typically has roof pitches that are substantially different from others in the nearby neighborhood. 3.2.2 Design for architectural integrity • In general, it is best to select a clear and distinctive archi- tectural st3~le rather than utilizing generic design elements or mixing elements from different architectural styles. • Building massing, roof pitches, materials, window types and proportions, design features (e.g., roof dormers), and other architectural features should be consistent with the traditions of the selected style. • Carry wall materials, window types and architectural details around all sides of die house. Avoid side and rear elevations that are markedly different from the front elevation. • Develop floor plans that allow the location and size of ~~indou~s to match the selected architectural style. For ex- ample, some st}~les emphasize the placement of windows in a symmetrical relationship to the entry. Some architectural styles require simple shapes and formal symmetry of the doors and windows I ~ 13 - 106 Residential Design Guidelines 22 Public Review Draft February 1, 2008 - Town of Los Gatos Example of the poor selection of a large and formal architectural style for the small scale and informal style neighborhood This style would have been more compatible with the neighborhood shown above Continuation of front facade materials and detailing onto other walls gives this Los Gatos residence good design integrity Town of Los Gatos BUILDING DESIGN 3 3.3 HEIGHT/BULK/SCALE 3.3.1 Develop the house plans and elevations together • Avoid compleb floor plans that require complicated building mass and roof forms. Work within the traditional forms of the archi~:ectural std=1e selected. Unless the architectural sty=le selected. clearly sup- ports substantial compleait5; generally keep building mass- ing and roof forms simple as is the norm fcr traditional architecture. • Avoid comple?c second floor plans and roof forms if that is not the norm for the neighborhood. 3.3.2 Height and bulk at front and side setbacks Two story houses may not be appropriate for e~=ery neigh- borhood. For neighborhoods dominated bj= one story homes, an effort should be made to lunit the rouse to one story in height or to accommodate second floor space w=ithin the roof form as is common in the Craftsman St3=le. When utilizing a cellar or extended foundation ~a=all, avoid. setting the first floor height at an elevation abo~=e grade that would be significantly different than those of the adjacent houses. Cellars are defined as an enclosed area that does not extend more than 4feetabove the existi~zg orfinishedg,~ade, and are ~zot counted in tl~e Floor ~Irea Ratio calculations, by Town Council policy. However, ifany pazt ofa cellar is abovegrade, it shall be considered in analyzing the bulk an~~ mass of the st,•ucture, eve~z if it is not included in tl~e FAR.:Il~e intent set forth in the General Plan is to provide hidden squarefootage in-lieu of visible mass." In the spirit of that intent, applicatr'ons with cellar space will be carefully evaluated to ensure that substantial e~forts Dave been made to reduce visible mass to ensure e-ompatibility with the site's inz~nediate neighborhood. For text of the Cellar Policy, see~lppendix C. Avoid eave lines and roof ridge lines that are substantially taller than the adjacent houses. Give special attention to adapting to the height end massing of adjacent homes. Avoid tall, unbroken front f;~cades a=hen other nearby homes have more articulated front facades urith horizontal u=all plane changes. In neighborhoods with small homes, try to place more of the floor area on the first floor with less area on die second floor. '~ -._.. t' -______ - __ --- ~: Some elevation of the first floor level may be acceptable and/or required in some neighborhoods 13 - 107 Residential Design Guidelines 23 Public Review Draft February 1, 2008 Avoid overly complex second floor plans and roof shapes like this example Substantially elevated first floors like this may not be acceptable in neighborhoods where they do not currently exist Town of Los Gatos BUILDING DESIGN 3 • Take care in the placement of second floor masses. Unless the architectural stsTle traditionally has the second floor front vaall at or near the first floor wall, set the second floor back from the front facade a nunimum of 5 feet. • The design of two story homes constructed adjacent to one story houses should include tecluvques to rr,;n;mi7.e their ~~sual impact and provide transitions in scale. Some techniques include: - Step down to one story elements near the side set- backs - Provide substantial side setbacks for the entire house - Provide substantial second floor side setbacks - Use hip roofs at the sides rather than gables • Avoid monumental scaled forms (e.g., towers or turrets) that contrast arith the neighborhood architectural forms. • Avoid bay w•indoa~s and other features that compete with the entry as the home's focal point. • Avoid the use of too many active building forms added to the mass of the building. An e~:cessive use of roof forms is a common problem. acep overhang with brackets . ~~ __ Material and pptor phange. 3.3.3 Provide visual relief for iwo story walls Some techniques include: • Belly bands (see photo below left) • Pop outs and bay windows • Material and color changes • Chimneys • ~~'ide overhangs with projecting brackets • Juliet balconies (see photo belo«T left) • ~fi~indow boles and pot shelves • Landscaped trellises and lattices This Craftsman Style house includes several features to mitigate the visual height of the side wall Masonry ahimrkey Projecting vrinduw pop oat I 13 - 108 Residential Design Guidelines 24 Public Review Draft February 1, 2008 Avoid too many building elements competing for attention Avoid too many roof forms that overly complicate the design Other two story wall mitigation techniques Town of Los Gatos t BUILDING DESIGN 3 3.4 GARAGES 3.4.1 Limit the prominence of garages • Avoid designs that allow the garage to dominate the street facade. • Limit the garage width to a ma~imtun of 50 percent of the total facade width. • Set garages back from the front facade. Limiting the width of garages and setting them back from the front facade can minimize their visual impact • Recess garage doors as much as possible frorr: the garage facade. • Consider adding trellises with landscaping over garage doors to soften their visual appearance. • Integrate the garage into the house forms in a manner that de-emphasizes the garage doors. -~~ - , 3~.~ -T. ~+` ei t-~ ' ~ ~~ '~s ~,~-~,.. z, :,? -.~_ ~_ ,, ~. -~,_. .~''- ~..

Some techniques include: • Using side loaded or split apart garages where possible • Accommodating additional cars in tandem spaces (see diagram on page 19) • Separating the garage doors • Breaking up driveway paving with landscaping and/or special paving 3.4.3 Integrate garage doors into the design with appropriate details • ~~Uindo~vs in garage doors are encouraged. • tfi~ood doors are encouraged. • Use wood trim similar to the house windows Utilizing individual doors helps to reduce the visual impact of multi-car ~araees ' 13 - 110 Residential Design Guidelines 26 Public Review Draft February 1, 2008 Separating garages can reduce their visual impacts in some cases Avoid wide driveways, as shown above, in favor of adding landscapine as below Garage door windows and trim in this Los Gatos house are closely related to the rest of the facade Town of Los Gatos BUILDING DESIGN 3 3.5 ROOFS 3.5.1 Unify roof pitches • Utilize the same slope for all primary roofs. • Roof slopes for porches may be lower than the primary roof slope, depending on the architectural stS~Le. • Dormer roof slopes may sometimes be steei~er than the primary roof slope, depending on the architectural style. 3.5.2 Avoid excessive roof form complexity Avoid multiple floor plan pop outs that produce multiple roof gables. Where roof eave variation is desired, consider vertical wall extensions and dormer roofs, as shown in the example below 3.5.3 Relate roof overhangs to the architectural style and to the surrounding neighborhood • Some architectural st3~les (e.g.,1\'Iission and Spanish Eclectic) often come in small and large overhang versions. In those circumstances, tailor the roof overhangs to the general character of the surrounding homes. I 13 - 111 Residential Design Guidelines Public Review Draft February 1, 2008 2~ Most architectural styles maintain a uniformity of roof pitch Some architectural styles have a different roof pitch for attached porches This is a good example of roof eave variation without excessive complexity s .

Provide a separate walkway from the sidewalk to the entry if that is the common pattern for adjacent and nearby homes. Avoid using the driveway as the wall~-way to the entry unless that is the norm for the neighborhood. In cases arhere the driveway is used, consider the use of modular pavers or decorative banding. 3.6.2 Design home entries with sensitivity to the architectural style • Most architectural styles have a distinctively unique entry ts~pe. Avoid using an entry type that is not part of the stele. For example, avoid using projecting entries, especially those arith an eave line higher than the first floor roo:F, for Ranch Sts*le houses or in Ranch StS~le neighborhoods. 3.6.3 Design entries with sensitivity to the surrounding neighborhood • Avoid large and formal entries unless that is the norm for nearby houses. It is often best to start the design consid- eration with an entry type (e.g., projecting or under eave porch) that is similar to nearby homes. • Houses on corner lots should consider using F~orches that wrap around from the front to the side elevation, as shown below This can assist in reducing the ~~isual height of taller side v,~alls, and in enlivening the side street frontage.

Be conscious of this fact, and organize the windows to comple- ment the style. 3.7.2 Match window types and proportions to the architectural style and to the surrounding neighborhood • Select window= types to complement the style of the house. Each architectural st5rle generally has one or tw=o w7ndow types that are traditional to the style. Double hung window=s, for e~:ample, are common features of Victorian and Crafts- man Sts-les w=bile casement w=indows are seen frequently in 1\tission and Spanish Eclectic sts~les. • Most architectural sti3rles feature windows that have either vertical or square proportions. Avoid horizontal window proportions unless the sty=le (e.g., Modern or Ranch St3Tle) is clearly supportive of that shape. Horizontal groupings of vertical and square windows are one means of providing visual balance to a facade design. • Limit the number of different window t5-pes and propor- tions to enhance the visual unity of the house design. • For second floor additions to e~:isting homes, match the windows on the original first floor. Match the size and shape of wrindo~v shutters to the shape and size of the w--indoor=s. Shutters that are large enough to cover the window=s, if closed, should be the goal. Hinges on shutters to allow their closure are desirable. Avoid very narrow shutters that are dearly not wide enough to cover the window opening. 3.7.3 Match window materials to the architectural style and to the surrounding neighborhood • ~Xrood windows are common in Los Gatos. ~X~ood is still the desired choice for styles that traditionally used w=ood. How=ever, today there are some window materials, such as ~rinyl clad w=ood windows that are not noticeably different from wood at a short distance. They may be used if their visual appearance matches wood. • Generall3; avoid metal windows. They may be considered acceptable for a Modern Style house, but would be strongly discouraged for all other st5rles. 13 -114 Residential Design Guidelines 30 Public Review Draft February 1, 2008 Group windows in a manner that is traditional for the architectural style Most architectural styles have vertically proportioned windows Windo-vs with some depth from the frame to the glass are desirable Town of Los Gatos BUILDING DESIGN 3 3.7.4 Design the windows with attention to matching the traditional details of the architectural style • Most architectural sty=les - except Mission, Spanish Eclectic or Modern -should have a=ood trim around tree windov,=s. The trim aridth should be matched to the sty=le, but in gen- eral, should not be less than 3 1 /2 inches u=ide. Head trim depth should be equal to or c=ider than the jamb casing, but not less than one-sixth of the opening width. • Projecting window sills and heads are strongly encouraged unless the architectural sty=le would not normally=have those features. • ~X~ood trim is also encouraged on stucco houses unless the window frames are recessed at least 6 inches fr~~m the out- side face of the wall. The use of stucco covered foam trim is strongly discouraged. Di~tided lights (i.e., larger window panes broken up into smaller pieces) are common in many home sty=les found in Los Gatos. Use either vertical or square proportions for the smaller window elements. Be consistent in the proportions (i.e., the ratio of the horizontal to the vertical dimension) of the smaller panes. Do not use snap in flat gr'.ds to simu- late di~rided lights. Use either true di~rided lights or one of the newer window systems that have dimensional muntins on both the exterior and interior of the glass along with a spacer muntin between the panes of glass. Use c:onsistendy for windows on all sides of the house. 3.7.5 Special window shapes and styles should be used sparingly • Avoid Estate Ho»>e S~j~le w=indows (e.g., tall arched windov=s) in neighborhoods a=here the homes are more Tnodest and informal in character. Bay windows should be designed with a base element to the ground or ~;rith supporting brackets at the base. Sloped roofs should be used and covered with a material trat matches the roof material or urith metal. Avoid using w~.ll materials beta=een the indi~ridual windows of the bay a=indo~v unless the window is large. Generally; bay windows loot: best when the windows are close together and separated by «~ood jambs that match u=ood sills and heads as shown in t]~e example to the right.

Industrial, municipal and some other users are required to follow regulations and obtain permits for discharge under the Environmental Protection Agen- cy's National Pollutant Discharge Elimination System (NPDES) permit program, which controls water pollu- tion by regulating point sources that discharge pollutants into waters of the United States. Although individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit, the potential for water contamination from copper is of concern to all Bay Area com- munities. The major uses of architectural cop- per in residential construction are roofs, gutters, and copper-treated composite shingles. Town of Los Gatos 3.8 MATERIALS 3.8.1 Use high quality materials • Use materials and mixes of materials that are consistent urith the architectural style selected. • Traditional materials, such as wood and stone, are most desirable, and strongly encouraged. Howes-er, the cost of materials and labor for many building components have led to the development of synthetic materials that are often hard to tell from the authentic ones. If any of these substitutes are selected, they must pass the test of looking like the authentic material at a distance of 3 feet if used on the first floor and 10 feet if used on the second floor. Avoid rough textured stucco in favor of a smooth sand finish. Composition roof shingles may be acceptable in lieu of wood shakes. However, shingles should be selected arith a texture that is similar to other houses in the neighbor- hood. 3.8.2 Select materials that are sensitive to the surrounding neighborhood • One a~ay of fitting a new house into an existing neighbor- hood -especially if the new house is bigger than many of the others around it - is to use materials drawn from the surrounding neighborhood. An all stucco house might seem out of character in an all wood neighborhood, but the predoninant use of wood siding urith some elements of stucco can often vaork. Where stone accents (e.g., clim- neys) are common in a neighborhood, the use of stone at the wall base and elsewhere can assist in making the new home seem better connected to its surroundings. • When using a min: of materials, avoid using too many materi- als -two or at most three are enough. Avoid an even split of materials (i.e., 50/50) on the facades. It is best to have one material as the doninant surface with the second material playing a lesser role. The use of a two-third to one-third ratio is a good place to start. 2/3 s#ucco 113 woad vall surface waU surface Srnail alone basQ 13 - 116 32 Residential Design Guidelines Public Review Draft February 1, 2008 Town of Los Gatos t BUILDING DESIGN 3 3.8.3 Use traditional detailing Treat openings in walls as though they mere cotlstructed of the traditional material for the style. For eaamp.e, be sure to provide substantial wall space above arches in. stucco and stone walls. Traditionally, uTall space above the arch mould have been necessary to structurally span the opening, and to make the space too small is inconsistent wzih the archi- tectural st~.le. Openings in walls faced oath stone, real or synthetic, should have defined lintels above the opening e~;cept ui I\tission or Spanish Eclectic styles. Lintels maybe stone, brick or wood as suits the style of the house. Treat synthetic materials as though they were authentic. For example, select synthetic stone patterns that place the indi~adual stones in a horizontal plane as they aTould have been in a load bearing masonry mall. Select roof materials that are consistent oath the traditional architectural style (e.g., avoid concrete roof tiles on a Crafts- man StS~le house.) 3.8.4 Materials changes Make materials and color changes at inside corners rather than outside corners to avoid a pasted on look. 4- wsai~ trrsltle YES ~~ a~ika Et+o a~rs~ ~a o io~r ~ OutsKfe Change materials No! at and oohs at outaFdr< inside tamers anmers 3.9 ADDITIONS/ACCESSORY BUILDINGS/SE(~ONDARY UNITS Follow the provisions set forth in Guideliine 4.9 on page 52. r" .!'.r .~ . _ ,.

Take care in selecting columns with an ap- propriate aridth to height ratio for the sty=le. E~:cept for a very few styles, the columns should have appropriate caps and bases urith proportions typical of the sty=le. • Pro~ride a well proportioned beam between the column caps and the roof. Size and detail the beam so that it looks like a conv=incing structural member. It should be risible both from inside and outside of die porch. A common problem is to make this element of the porch too small or to face it with a material (e.g., siding) that would not carry the a=eight above if it were structural. For most architectural std=les, molding and trim will di~ride the beam vertically into three major elements of varying height. • Railings should generally be constructed of a=ood unless the specific architectural stl=le allows for metal or stone. Provide both top and bottom rails with the bottom rail raised above the porch floor level. • Vertical balusters should be appropriate to the architectural sty=le. Some are quite simple while others may have special shapes. • Take care in designing porch stairs. They generally should match the porch floor (e.g, wood) or the sidew=alk material if other than concrete (e.g, brick). 1~'ote: All porches are ea~ected to be usable and Dave a vninamum depth of 6 feet orpreferab>~ more. 3.10.2 Balconies • Avoid balconies that project more dean 3 feet from the face of the building unless they are ty=pical of the architectural sty=le. • Pro~ride supporting brackets or beams that are large enough to clearly appear to pro~ride structural support for the bal- cony. • Railings should be designed as discussed above for porch railings. For longer railings, intermediate posts vdth caps and bases should be used to break the railing into smaller increments. 3.10.3 Brackets Brackets at roof overhangs, balconies and bap windows should be designed to extend to fascia/balcony edge/pro- jectingbay front or slightly beyond. Avoid stub brackets that do not appear substantial enough to support the element ~ above. 13 - 118 Residential Design Guidelines 34 Public Review Draft February 1, 2008 Porch beam example with good depth and details Some architectural styles suggest simple columns and railings While others require much more refined details Town of Los Gatos BUILDING DESIGN 3- 3.10.4 Chimneys • Chimneys should extend to ground level. Avoid cantilevers above the ground. • Chimney materials, size, shape and height should be appro- priate to the architectural style and to the scale c f the house. Avoid undersized chimneys that are too narrow and too low Add chimneys for gas fireplaces when the architectural style would normally feature chimneys. • Provide chunney caps that are interesting and appropriate to the architectural st3=le. 3.10.5 Roof flashing and vents • Paint flashing and vents to match the color of the roof. 3.10.6 Skylights • First, consider the use of roof dormers or clerestories instead of skylights. • Use flat profile skylights rather than domed models. • Select glazing to avoid the feeling of roof bea~:ons or lan- terns that are highly risible from the street or ~ieighboring properties. 3.11 PRIVACY AND SOLAR ACCESS 3.11,1 Minimize shadow impacts on adjacent properties • Locate structures to minimize blocking suri access to liv- ing spaces and actively used outdoor areas on adjacent homes. 3.11.2 Minimize privacy intrusions on adjacent residences • Windows should be placed to m;n;m;~e ~riews into the living spaces and yard spaces near neighboring homes. • When windows are needed and desired in side bLUlding walls, they should be modest in size and not directly opposite ~vindo~vs on adjacent homes. • Where possible, second floor windows that might intrude on adjacent property privacy should have sill heights above eye level or have frosted or textured glass to reduce ~7sua1 exposure. • Bay windows should be avoided on side «=alls where they v,=ould intrude on adjacent residents' privac3: • Second floor balconies and decks should be used only v=hen they do not intrude on the privacy of adjacent neighbors.

Avoid panels vrith slopes that are different than that of the roof. • Integrate the design of panels into the design of the roof. Avoid stacked-on appearance. 3.11.5 Minimize exterior lighting impacts on neighbors • All exterior light fixtures should utilize shields to ensure that light is directed to the ground surface and does not spill light onto neighboring parcels or produce glare v>hen seen from nearby homes. • Decorative residential light fixtures should be chosen rather than strictly utilitarian security lighting fixtures.

Sustainabilit~= refers to the use of natural resources in a manner that ensures their continued availability to future generations. The Tou=n believes that historic preser~=anon is the most sensitive path to sustainability, but recognizes that this is not always possible, and that an emphasis on green building can be an effecti~,=e means of promoting the conser~=anon of natural resources. The term green building is often used to relate sustainability to development. Green building addresses a broad range of techniques to reduce the consumption of natural resources during construction and over the lifetime of a home. These include designing structures to be energy and water efficient, utilizing building materials that reduce resource consumption and improve indoor air qualitl; and taking ma~iunum advantage of renew=able energy resources. The Green Building Strategies and Materials in Appendix D contain design strategies that majimize the use of renev;=able energy resources for heating, cooling and lighting, additional.strategies that conserve energy and water, a list of building materials that reduce the consumption of nonrenewable resources and improve air qual- it3; and a list of various sources for "green building" information and their web sites. i 13 - 121 Residential Design Guidelines Public Review Draft February 1, 2008 3~ CITY OF CUPERTINO 10300 Torre Avenue, Cupertino, California 95014 DEPARTMENT OF COMMUNITY DEVELOPMENT REPORT FORM Agenda Date: May 13, 2008 Item Summary: Discussion of the R-1 Ordinance first floor to second floor ratio requirements RECOMMENDATION: Discuss this item, then note and file this report. BACKGROUND: On Tuesday May 6, 2008, the City Council amended the Planning Commission work program to include a review of the R-1 Ordinance first floor to second floor ratio requirement. The Council directed that the Plaruling Commission wrap up your work in September and present the recommendation to the City Council in October 2008. ' DISCUSSION: The Council direction limited the amendment to considering if the second floor to first floor ratio should be changed. The Commission is not authorized to evaluate changing second story setbacks or other elements of the ordinance such as the overall floor area ratio. Council members voiced concern that the 45% second floor to first floor ratio inadvertently encourages homeowners to increase the size of the first floor to ensure the second floor proportion is large enough to accommodate the desired number of bedrooms. Also, concern was expressed that the current formula results in a repetitive style of "wedding cake" architecture. For example a "Victorian' or "Queen Anne" style of architecture is difficult to design with the current rule. Staff anticipates that the Corrunission will need to address the amount of exposed second floor wall plane as this rule directly relates to the issue of potentially allowing the first and second floor walls to align. The Commission will need to assess if some alternate method of breaking up the ~vall plane should be considered such as awning or trellis elements. Finally, the Commission may need to consider alternate review procedures for applicants taking advantage of any amendments. Staff will send out acity-wide mailer and attempt to provide articles in the Cupertino Scene and on the web site to keep the public informed of this review. Staff anticipates the item will be ready for the Planning Commission in July 2008. In the meantime staff will evaluate if this change will potentially delay any other work program items. _ Submitted by: Steve Piasecki, Director of Community Development 13 - 122 Cupertino Planning Commission 4 September 9, 2008 Vice Chair Giefer: • Concurred with Com.

MCA-2008-03 Municipal Code Amendment to the Single Family Rl Ordinance City of Cupertino (Section 19.2.8.060) regarding the allowed ratio of the second Citywide Location floor building area compared to the first floor building area. The Revised Ordinance will"consider adjusting the allowed ratio to facilitate greater architectural diversity, but will not consider increasing or decreasing the total allowed building area on an Rl lot or changing the required second story setbacks. Continued from the August 26, 2008 7lanning Commission meeting. Tentative City Council date: Not Scheduled. Gary Chao, Senior Assistant Planner, presented the staff report: • On May 6, 2008, the City Council as part of their 2007-08 work program directed staff to look at review of the R1 ordinance specifically :regarding the second floor to ground floor ratio. The direction was to have the Planning Commission review and provide recommendations back to the Council by Oct. 2008. In addition, as part of the process, staff will be introducing one or two minor suggestions unrelated to thy; second floor ratio housekeeping items. • On July 8, 2008 the Planning Commissicn reviewed the initial proposal from staff and provided direction that a more focused ordinance framework should be provided that tailored guidelines and principles applicable to tl~e city of Cupertino issues. In addition, the " Commission wanted additional images and l~aphics more pertinent to the community and the discussion whether the city architectural consultant Larry Cannon should also be involved in this process. Staff has since communicated with Larry Cannon and entered into a preliminary contract with him; he is prepared to go pending Commission's direction this evening. • In July, there were some concerns raised by "the Commission. The first one was on the lack of prescriptive nature"of the proposed new de;~ign review process. To clarify in response, the intent from the City Council to go through this exercise to potentially change the ordinance"is to facilitate design flexibility; and in order to accomplish that, you have to have more flexible standards to achieve the flexibility of options to provide to applicants or homeowners or architects in this case. Staff has since then added more specifics into the framework, tailoring it to the Cupertino issues. ~ Concerns were raised that this might promote box style homes in Cupertino. Staff has established precise objectives and intent inta this process so that when property owners and 13 - 123 Cupertino Planning Commission 5 September 9, 2008 architects wanting to go through this voluntary process, will understand what is in store and what is expected of them, in particular architectural style needs to be identified and specific visual relief measures shall be applied. • Why create a new process; why not use the current process? For example the exception process could entertain a project potentially having a second floor larger than the 45% rule, the only comment regarding that is that the exception process does not currently have any specific provisions that allow us to ensure visual release on large wall planes and such. The exception process is also costly and intimidating to average homeowners and architects as well. • What staff is proposing in terms of review framework: The applicability this new process we are suggesting to you would cover any application as proposed to have a residential home, a second floor larger than 45% of the ground floor area. We are not suggesting the overall FAR of the site be amended or that the minimum setback requirements also be retained and preserved as well. Those will not change as part of this proposal. In addition it is important to note that the existing quite prescriptive process that you have now are still intact; any property owner wishing to go through the current process and have no desire of wanting to propose a house over 45% second floor, can go through the current process without having to deal with the additional guidelines and objectives to cover. He reviewed briefly the comparative table between the current ordinance and the proposed ordinance, to give a sense of what is being changed and what is not. The three areas to highlight are the second floor to ground floor ratio; we are suggesting that be allowed to exceeded. Also in conjunction with that rule, we are proposing that the second floor setback surcharge be exact for those who are going through this process from our conversations with local architects; you cannot have one without the other because homes are expected to be larger; setback surcharge would prohibit that from happening. Therefore, in their suggestion to us that also should be lifted as well. In the change there is a lot of design techniques that we are adding into the ordinance that will cover and mask some of the potentially larger walls and blank walls with trellises, arbors and balconies. • Lastly the second floor 50% exposed wall rule; we are suggesting that rule be redefined to allow the use of the new architectural relief techniques, architectural features as a way to address that rule or satisfy that 50% rule. • Said there doing this because the existing Rl ordinance limits the design flexibility due to the second story size restriction; as mentioned previously some of the second floor surcharge also• is restricting as well, and it dictates what it is meant to be; what is meant to accomplish is to make sure that the homes are wedding cake and are set back quite significantly and you can see that from the example pix provided. Also what we are seeing is that this sort of architecture is more predominant now in the neighborhoods and they are pretty much taking over and the concern we are seeing is that is all we are going to get; we are not going to get anything other than these until 10 or 20 years, and that is going to predominate the pattern, styles, the community and that is a concern. • Inadvertently, ground floors are being maximized to ensure that the applicant's homeowners get the sufficient maximum allowed second floor because the ratio exists. The only way to have a large second floor is to maximize your ground floor; everyone is stretching the envelope to the max on the ground floor to accomplish that. • The objective of the new process is to allow greater design flexibility, at the same time not compromising good design; and also to address some of the known issues previously mentioned and that Cupertino cares about. Those are usually articulation of walls, addressing blank walls, embellishments, visual relief of mass and scale of second floor wall planes. • The design principles previously mentioned; when an applicant comes forward wanting to go through the voluntary process, the Director of Community Development may grant approval to allow the proposal to exceed the 45% second floor ground floor ratio provided the seven principles outlined on Page 2 of the staff report are met. • He reviewed the visual relief techniques listed on Page 3 of the staff report. 13 - 124 Cupertino Planning Commission September 9, 2008 Other related minor ordinance changes that the Planning Commission should consider is the exception of the second floor 10 feet setbacl~: surcharge requirements and also the 50% second floor wall exposure requirement. Staff is bringing to you the more specific framework asking for directions and comments from you if you feel comfortable with it, provide us with directions, give us the green light and we will talk and communicate with the city architect and come back to you with a more precise ordinance amendment language in addition with pictures, illustrations, to better help the public understand some of the principles we are dis~;ussing. Staff's recommendation is for the Planning Commission to review the framework, give feedback, or alternatively, if you feel comfortable with this approach, you can recommend it to the City Council. Com. Brophy: • What is the difference between the current review process for two story homes and what the process would be for those two story homes that would ask for a second floor greater than 45% of the first floor. Gary Chao: • Staff is proposing that the process be the same timeline to make sure that it is not going to be a deterrent for people to go through. However, the findings, guidelines and principles that we use to review the two different applications would differ. The current process under the current rule if you stay under 45% seco~id floor, as you know the ordinance is pretty prescriptive. As long as the color is not out of whack with the neighborhood, most likely it is an approval; that is what it is designed to do. It is the prescriptive nature in the Rl ordinance. With this new voluntary process for people `wanting to exceed the 45%, what we are saying is, that in exchange to allow people to have a larger second floor, we are suggesting additional design principles which were outlined ah-eady earlier that are not covered by the current Rl ordinance. That should be evaluated and considered and found to exist on the proposal in order for the city to approve the application for them to exceed 45%. Com. Brophy: • When I look at the list of design principles, in theory shouldn't we be applying this currently to any two-story home that goes through review; I'can't see the difference. Steve Piasecki: The intent of the existing rules was to be highly prescriptive and not have subjective review of whether the materials are compatible with t:he architectural style that is being proposed; nor necessarily whether the materials are of 1-igh quality or whether you followed the basic principles of symmetry and balance, so you ~~ould have asymmetrical mixed up material house and still get through with that prescriptive process. That is not to say that we don't work with the applicants and point those things out to them and try to encourage them to incorporate them, but we cannot require it; it is not part of the purview. This is now saying that with these design principles, we are more concerned about symmetry, balance, consistency of materials, and incorporating these other design features so we will exercise some more subjective review. Com. Rose: • Said she was looking at the design principles that would be the role of Steve Piasecki to determine whether they have been met on each project. How is it defined what is considered a high quality material? 13 - 125 Cupertino Planning Commission 7 September 9, 2008 Gary Chao: • It is usually a combination of many different things; how the materials tie in with each other; the compatibility of the material to the style of the home; sometimes people want to build a Mediterranean style house or Spanish style house and a true Spanish style siding is usually more smooth and hand troweled finish, higher quality than just sprayed on materials. It is difficult to answer; it is not always defined by cost, but is more of an architectural theme that has to be consistent. Steve Piasecki: • Said the point was well taken that it needs to be defined better, either by example or some other way of defming it so that it is not confusing to people. We know that if you are proposing a Spanish style home, you probably don't want to use the metal faux Spanish roof material, even though that might be lighter and cheaper. Staff would coach the applicant to meet that part of the requirement that they would need to eliminate the T-111 siding or put in different materials in keeping with the Spanish architecture. If they disagree, they could take it to the Design Review Committee. He said relative to the design principles, it is the intent that the applicant will reasonably comply with all seven design principles. Vice Chair Giefer: • Asked how staff would address a request to build a house that has an overhang, where the second story exceeds the ground floor level. Could you do this given what you are proposing; and what would be the reduction on the back end of it; would you allow them to exceed 100% in order to achieve that. Gary Chao: • The way the ordinance is proposed it doesn't have a maximum limitation, but is more design driven. From talking to some architects, we were discussing ways to articulate second mass and the idea was that you don't necessarily always have to recess and indent from the ground floor. There is very nice, beautiful looking homes that have nice gable elements that project out with corbels underneath, so there is a lot of opportunity and we are excited about this for that reason, there are projections you can consider, overhangs that you can consider, that would meet the intent of the ordinance and breaking up mass as opposed to setting things back. • Said he had not thought of the second question in terms of reduction and tradeoff; again, it is going to be like a package that we have to look at as a whole. The way the ordinance is being proposed, you could potentially exceed that 100% ground floor to second floor ratio. You could say as a Commission your recommendation is to stop at 100% or whatever other percent you are comfortable with. Chair Miller: • Said that the new ordinance specifies that new buildings shall be in conformity or compatibility with existing buildings on the street. How do you reconcile the attempt to bring some more diversity into the neighborhood vs. our existing ordinance which says we want the same thing on the street. Gary Chao: • We have people making that argument now with the current ordinance, somebody wants to build a Mediterranean house in a Ranch or Spanish neighborhood and the way the ordinance has been interpreted up to this point in terms of compatibility is not that house designs have to exactly mimic or replicate the existing predominant style of the neighborhood, as long as the material color massing scale respects the adjacent neighbors house. Basically that constitutes 13 - 126 Cupertino Planning Commission 8 September 9, 2008 • being compatible with the neighborhood. Ii: is a good thing to allow different flavors of style homes in a neighborhood. Chair Miller: • Said there maybe an inconsistency with the existing wording of the ordinance. Steve Piasecld: • I think what staff is saying is that the problem you are describing, doesn't go away with this. The fact that we are asking people when thc;y bring their building in, tell us what it is, tell us what it is, what is this animal you are tryin€; to construct, and if it is Calif. Ranch fine, if it is Craftsman fine. But your point is well taken, you are still going to get potentially the argument that we don't have Craftsmen homes in the neighborhood, therefore what are you doing building a Craftsman style. Staff's }point is that you need to be at least respectful of mass and the materials utilized throughout th.e neighborhood, not completely ignore it. • We try to be fairly flexible today, we will continue to try and be flexible, but it is a good point; that conflict still goes on. Chair Miller: • Relative to the architectural style selected, it implies that there is another level of work that staff is going to take on to inspect the derails of each house to make sure every detail is consistent with the style. Gary Chao: • In concept yes, if a person wants to do a Craftsman style house, we don't want him to propose an element, an entry feature that is from another style and doesn't jive with the design. What we are saying is whatever style they decide: to go with, they should do the best they can to ensure that all the features, embellishments, colors, materials, shape of the, roof, design of the windows are consistent with that style, to make the house coherent and nice looking. Chair Miller: • Expressed concern that they may be getting into an area where there is way too much interpretation on the part of staff in terms of ~,vhat an applicant can and cannot do. Steve Piasecki: • Said the Commission could suggest to the City Council that every one of these go to DRC and have an open process where they can have that discussion. Chair Miller: • Referred to No. 7 of the design principles `5.he design shall reflect symmetry, proportion and balance", and said that it was already in the: ordnance, and he was concerned with that. He illustrated a book by Dahlen Group, a renowned architect who shows lots of good and tasteful examples of symmetry and asymmetry. Saicl he always had a problem with the issue of lining up all the doors and windows as it doesn't ahvays make good architectural design to do that. Steve Piaseclci: • We have heard both sides of that argument acid maybe we could defer to some of the architects to talk about; and we intend to see this in other design guidelines, that in balance; that we would like people to think about achieving a degree of symmetry. The asymmetry you tend to see in homes that can be tasteful, is usually :not a very dominant asymmetry; it is not a heavy reliance on it. . 13-127 Cupertino Planning Commission 9 September 9, 2008 ~ You could take No. 7 and say as a rule that you shouldn't strive for this, that some variations are acceptable, but they need to be done tastefully. Com. Kaneda: • This modification only applies when people are proposing to go over 45% on the second floor. (Staff Yes; if they exceed the 45% ratio) If they stay under, it is the current rule. I would suggest we think about is if we are going to do this, let's do it or not do it; not write this arbitrary. You get to some arbitrary number and then we are going to make the houses look nice and otherwise they don't look so good. • Said he agreed about the language regarding being consistent with the neighborhood and the language .that talks about architectural diversity; and said it was confusing to him personally, and also to the community, because so many times people come to the Commission and play the "not consistent with the neighborhood card" as a reason why a house should not get built. • In most cases I like diversity; it is nice to have some diversity and if you are just looking for good architecture and consistent massing and materials, why don't we just say we are looking for good architecture consistent massing and materials, rather than say it has ~ to match the neighborhood. Com. Brophy: • Said since the last public hearing on the item, he has been struggling with the issue that Vice Chair Giefer raised, which was more the social dynamics of how this would be applied; that there is already a perception in the community that the process by which either the staff, Commission or Council goes through in making decisions, has an arbitrary or unreasonable procedure; and here where we are dealing with the whole situation of review by its very definition, there is a certain amount of that the process is a subjective and judgmental kind of process; and I am wondering whether or not by opening this up in this direction if the irritation from either would-be home builders or neighbors of the project would be greater than whatever aesthetic benefits that we would gain from this process. Gary Chao: • You could ask some of the architects in the audience for their feedback. Most of the architects I have worked with have no complaints; they are pleased with the process. Having said that, the key is that this is a voluntary process; however, the way the current ordinance is established now, it is working; people are used to it. For those who do feel up to the challenge of wanting to go through this more of a creative process, they can still opt to build under the current rule and go through a more prescriptive nature and get their building floor plan approved. • For the architects who are usually looking to do good designs, they look at these rules; these are some of the things that they would do usually regardless of whether there is provision for it or not. However, the feeling is that they are limited because of the way the can ent ordinance is set up. For those who want to do something creative and out of the box, they don't have the tools or mechanism to do that. This process allows for that, and at least from my conversations with some of the architects that do a lot of work, they feel comfortable with these rules because they are fairly basic. Com. Brophy: • The would-be builder of the home has the option to opt into these rules; neighbors who might oppose the project don't have that option. 13 - 128 Cupertino Planning Commission 10 September 9, 2008 Vice Chair Giefer: In areas of the city where you have smaller lots such as Rancho Rinconada, have we thoroughly thought this out on the 5,000 ;square foot lots, where I can build 100% of the second story but the lot size is so small that it still may be difficult for me not to have a house that is too massive or out of scale with the neighborhood. When people talk about neighborhood com~~atibility, what it boils down to is mass and scale and if you are on a small lot, I can see areas where that may be problematic. Where someone is on a corner facing another street, what is what is interpreted as their side yard setback (Garden Gate); their privacy may be intem~pted by an adjacent property looking down upon them. How do we make sure that the programs still work and that the massing and scale is not overwhelming for small lots in particular. Gary Chao: • Many property owners having lots under E;,000 square feet that are less than 50 feet wide; have a difficult time meeting the current rule and after applying all the articulation rule, the setback, you end up with literally a hallway on the second floor. There are arguments both ways. You could stipulate that there may b~~ some special consideration for lots under 6,000 square feet or Rl-5 areas; there may be some special provisions to get at what you are talking about, ensuring that the mass is not excessive;. Steve Piasecki: • Said if you have a 5,000 square foot lot, 50 ley 100, the 45% overall floor area ratio limits you to a 2,250 square feet home. Already you have a smaller house. The setback requirements of 10 and 15 on the side yards force that house into the center of the lot as they would on a larger lot. You are getting 1125 square feet, let's say you want 100% on the ground floor and on the second floor. You have the setbacks of 11) and 15, you are at 1125, you have to provide adornments and trellises or something to break up that building mass. Proportionally everything stays about the same and it doesn't really matter; you can argue that the position of the setbacks doesn't change as you get smali~er. You have a greater obligation in terms of the relative size of your lot compared to a 10,000 square foot lot. Vice Chair Giefer: Said that was the argument made when they changed the R1 FAR to 45 feet, that it was scalable; but on smaller lots just because you. are so much closer to your neighbors than on the larger lot, it is more problematic having 45% coverage. Steve Piasecki: • You could opt for some kind of scaling, although the Council said do not look at the FAR so you can still say we think it should be scaled. I think you are getting at that, because of the setback requirements and the FAR, it gets sealed down anyway. It may be more problematic for somebody who has an extraordinarily n~~rrow lot, to accommodate the 10 and 15, if you have a 35 foot wide lot or 40 foot wide lot; you can start to see how those eat into your developable area. • If you want to when we come back, we can try to find examples of the 5,000 square foot lots and show you how that might look. Com. Rose: • The way this has been approached, it sounds like everyone is coming to Planning saying I want to build a Craftsman house but I can't, so I am going to build a wedding cake Mediterranean. Is that is what is happening? You are getting a lot of frustrated people because the design they want, which like these pic~i.~res, they are beautiful homes, that people are 13-129 Cupertino Planning Commission 11 September 9, 2008 coming in with .that vision and when they look at going through the exception process and the cost of that, they are backing up and saying they are actually fine doing the tier. Steve Piasecld: • Said his impression is that it isn't that so much; people aren't saying they want to build Frank Lloyd Wright Craftsman and you are making them build Mediterranean wedding cake. More likely what is happening is, they want to put a little gable end on their house and cannot do it; or the requests coming in are fairly minor things that are prohibited by our ordinances; they don't have any flexibility at all, so they end up with the wedding cake because everything pushes them to be uniform. Com. Rose: • I am going on the assumption of what I see primarily here that comes to us as well as what I see driving in our neighborhoods, is that it seems to be that the Mediterranean style is predominantly what people want to build when they build in Cupertino, so my question would be, is a gable considered consistent with the architectural style of a Mediterranean home? Steve Piasecld: . • Said that Page 2-8 shows a Mediterranean or Spanish home with a gable. He said the ordinance was designed to please the neighbor. Chair Miller opened the public hearing. Jennifer Griffin, Rancho Rinconada resident: , • Requested that all speakers given the same amount of speaker time, whether a resident or an architect. Said that the method of giving some speakers extra time was highly unusual and requested that the speaker time be timed. • Illustrated an article from S.F. Gate, about a community in Manteca and what happens to the community with 100% buildout on the second story. She presented photos which showed the articulation in the front area of the homes; the side walls are 100% buildout with no articulation; and the two-story rear of the homes have no adornment. In a different neighborhood, she homes where they did the fronts, but not the other three sides. The size of the homes and the fact that every developer who came into my neighborhood cut down every street tree. We have boxy big square homes all over my neighborhood, they are all over Monta Vista, a lot of them in Garden Gate. Cupertino itself was hit with this. • Said that she felt the city was a heartbeat away from monster homes. It is going to become neighbor to neighbor as it was in the pre-90s and in 2000 when Cupertino adopted a new building code that reduced the size of the homes. She said six months from now there will likely be the desire to go to 35 feet again and to have the homes that are buildable on the lots, where currently a 5,500 square foot lot can take 2,400 square feet. • Many people were relieved when they annexed into the city because there were protective building codes; that is why we had the choice of coming into Cupertino. We are on the road now to having each one of these thrown down and I think that if we go down this road we need to have an ordinance for lots less than 6,000 square feet to have a special zoning area where you cannot have over 45% or whatever the City Council has decided. 45% is still what the City Council has decided until otherwise changed. • Said she lived through the experience for 5 to 8 years with the battles of annexation; they would be opening a Pandora'a box and it would happen all the way across the city. • Eight years and nobody believed building codes could change; Rl is being torn down. When they went through this two years ago, some of the developers said you couldn't get three bedrooms in 600 square feet on the second story; some people in Rancho Rinconada put four 13 - 130 Cupertino Planning Commission 12 September 9, 2008 bedrooms in 600 square feet. Two years ago the second story quota was increased to 800 square feet; architects still claim today that you cannot put three bedrooms ir.~ 800 square feet. There are two plans recently in my neighborhood, one across the street, and they have three bedrooms, a massive master suite and two other bedrooms, full baths; it can be: done. What we decide here is going to affect all of Cupertino; but it is also going to be devastation for Rancho Rinconada. Those examples shown earlier by staff look like gorillas in tutus; I wouldn't want any of those homes next to me. We have a lot of boxy structures in Rancho Rinconada; they are too high, too big; now the trees have grown up, you cannot really see them; there is nice people who live there, but I wouldn't want my neighbors to build anything that exceeded 45% near me; I think there are people in Cupertino who don't realize; was (:reaton notified? She said they had not received citywide notification on the project in nearly a month or two; and it should be heavily noticed before it goes to the City Council. The City Council should not take their final vote in October; it is too far encompassing; getting rid of the second story surcharge. She recalled the first time that w~is applied to homes in Rancho Rinconada in 1999 and 2000 because when they were in the ~~ounty, they were put under the auspices of the Cupertino Building Code. Said she had more things to discuss but wa;~ not sure of her time limit. She commented that she had a Bachelors degree in Chemistry, and hoped that the architects didn't get to talk longer than she did because she did not consider their training any more effective. Dick Fang, Cupertino resident: • Said he was a professional designer in the area for 20 years. Tonight there is a chance to raise the second floor and ground floor more than 45%. He said he read all the staff reports and there is a sense that if you build a larger :second floor, you should get nicer architectural features; but he worried that things such as processing timing or processing to get approved will get more complicated. • Said his clients want only 3% or 5% more; :.f you go more than 45% they only get 3% or 5% more than you go to another level of the stuciy; that probably is not fair for the small lot; most of Cupertino lots are 6,000 square feet; Rancho Rinconada area is 4,500 or 5,000 square feet. • Said if the desire is to open from 45% to up to no limit, he suggested current zoning ordinance change to 45% to 50%, all requirements sta;~ the same; then people can more easily get either three bedrooms of decent size upstairs or bigger size they can get four bedroom upstairs. • They might not go to 100% of the house, 100% of the second floor; if you could split by 50%, lower than 50% keep the ordinance as is no~~v. If people build more than 50% to 100% of the second floor, they need to think about style wise, material wise, everything, so that might be fair to all my clients' wishes. Steve Yang, Cupertino resident: • Practicing architect for 27 years. • Relative to concept, Cupertino hinges on 45, this number for about 5 years. Prior to that a smaller number and then because most of th.e community thinks it is a monster house, let me add to that one too, when Ms. Griffin sho~~ved the photo on the screen, I thought it was a disaster. True; however, that property con-dng to a PD project is not a single family stand alone house, so it probably should have considered two types of approach for 45% or increase more, whereas for PD or single family it world come into two different solutions possible. • When you design a home the Commission brought up 100% buildout; I totally disagree with that. The reason is that being an architect designing a home you can see it, giving a size of 5,000 to 7,000 square feet you should go first floor is heavily used space, the second floor would be the bedroom normally; if 100% b~.~ildout you probably violate the 45% ratio of the FAR, that is automatic. However, I support this increase. As far as up to 100% buildout of a 13 - 131 . Cupertino Planning Commission 13 September 9, 2008 single family stand alone house, in my dictionary I don't think so. I never see it; and the city of Cupertino invited a good architect to review the design before the final. • Said he had a recent project in an undisclosed city; which is called a small lot single family; and it looks like 100% bit it's not, but is a well designed one with two story, about 800 square feet. • That piece of architecture is well done plus they have an architectural review by not only the Planning Commission but also outside consultant. Before they got it approved it had to go through many layers, so I agree with this proposal of 45%. Steve Piasecld: • Clarified that the city does not use an outside architect for single family home remodels; people come in and they meet the prescriptive requirements of the ordinance; we don't go through Larry Cannon. We do for multiple family projects or single family developments where we have five or six homes; but we don't do it for the individual single families. The practice was abandoned because the ordinance became very prescriptive and it was costly and took too much time. Tom Tofigh, Cupertino resident: • Said he wanted to share his experience of the process of building a single family home he purchased in Cupertino about 2004. He realized that the home was built about 56 years ago and was not energy efficient. Unfortunately the process took almost 2-l./2 years by the time they received the permit. He said the people in city hall and planning department were very nice and he appreciated all their patience. He spent about $500 just for copying costs alone and his construction loan was in process. By the time he got the permit and the credit crunch arose, he lost the construction loan and was out about $40,000 just on permits, etc. The flexibility was not there, maybe if you trained the architects who do single family homes, they know what all the codes mean and how to go about it and things can go faster, but the process took such a long time that I missed the opportunity to build a new home for myself. I got to a point where there was only the demolishment permit that I needed to get, but I didn't have the financials to go forward with it. Part of it had to do with giving too much leeway to the neighbors regarding what they like to do, they didn't like the style and they wouldn't say what I could do about the style so I could change it. That process took such a long time. • He asked the Commission to show compassion to the people building a single family home for themselves vs. somebody who is professional and building a large number of homes and have a lot of experience. Chair Miller closed the public hearing. Chair Miller: • Steve Yang brought up an interesting point; we have two standards, one for single family homes and one for PDs. In PDs we do this as a matter of course go above 45%. Can staff comment on that difference in treatment. Steve Piasecid: • What he is referring to in almost all the PD examples of their higher density projects, Murano, or Astoria, these are projects in the 10, 12, 20 units to the acre category in most cases.. There are other examples of conventional. single family and if we have multiple units being built and they are developing an Oak Valley or four or five unit development, we are more concerned about how to fit that in, how to make those units work together, so we refer to the architectural 13 - 132 Cupertino Planning Commission 14 September 9, 2008 • advisor for typical single family developn^~ents, one house at a time, the remodel example; again, we don't; we found that the prescriptive requirements work fairly well so we just use those. • If you had a one unit PD project, you would have to go through the architectural advisor. The rationale is partly you are being given greater flexibility in a plan development with small lot single family homes a conventional home is being allowed. There are stricter design requirements for PDs and in return for that,l:hey are given the flexibility to go up to 100%. Chair Miller: • What we are proposing here, is it is not go::ng all that way, because we are less restrictive in PDs on all requirements including setbacks ~md lot size. Com. Kaneda: • Said he had mixed feelings; and he strongly supports architectural diversity; the wedding cake style developed in Cupertino is highly inefficient from a construction standpoint, but it requires builders to use much more material and it is environmentally not the best way to design. There is this issue of controlling ma;;s. The conflict is between having a nice clean set of prescriptive rules which is what we are originally trying to do; so there is not a lot of subjective review involved in the process; and relaxing those rules to allow flexibility, but trying to control the quality of the buildin€; by putting in subjective review. The concern I have is we are going to create one of two things; either a bottleneck because somebody has to review all these designs and I don't agree v~rith the idea of just doing it on projects over 45% where the second floor is over 45%; I think you should either do it or not do it. Now you are creating a situation where all these project` have to be reviewed by someone; and the other thing is because it is so subjective, there: are horror stories from other cities about the architectural reviews where people just have their pet look they are trying to achieve and if you don't match it then they just dig their heels in and you cannot do. On the one hand Palo Alto does have beautiful buildings, but there have also been many complaints in the architectural community about how hard it is to build in Palo Alto. ~ If we get into discussing wordsmithing different parts of the ordinance, there are other comments to make. Com. Rose: • This is an important issue to discuss because there are areas of Cupertino that are experiencing new home development on a lot by lot situation at a rapid rate; most of them are pockets annexed into Cupertino in the last 15 years. What I think drove that annexation for many of those communities, was the desire to get a~~vay from the county's building ordinance which was a lot more lax. The ratio for the first t~~ second floor was up to 100%, and years of that and watching this new trend toward building a more modern and more current home design, we were seeing a trend toward very large homes without any architectural features and everyone just maxed out the lot. That supp~~rted a lot of the annexation that happened in the last ten years very smoothly for the city of Cupertino which worked very hard to try to lure and annex those communities. • The biggest carrot they were dangling was a process for building and also an Rl that was going to be stricter and more considerate acid include such amenities as a privacy landscape plan for homes with second floors, etc., things that we were not experiencing. I live in a neighborhood that is transitional, under the county jurisdiction. I do think we have to be cautious here, there was a lot of annexation done smoothly because of the carrot of support in what was happening with development in these neighborhoods. That being said, when we look at, again, as someone who lives in, a neighborhood, any Rl changes that happen in the next 6 months, I will be witnessing within weeks and months, and constantly I see homes 13 -133 Cupertino Planning Commission 15 September 9, 2008 every four months being built around me. I am aware of this and if I could speak for people in those communities where there is a lot of turnover; there is a lot of neighborhoods in Cupertino that do not really ever get to see the R1 in action; they are not as transitional and I think when you live in a community that is transitional, you welcome older homes that are outdated being replaced with newer homes; it makes everything look better; often times sidewalks are improved, street lighting is improved, so the connotation that development is a negative thing for many of the older neighborhoods is false, and with that I think there is some frustration that there is a predominant look and feel of a Mediterranean style and they are larger homes, so they often stand out, but I don't think the changes that we are talking about here are really the right way to solve the "problem of wedding cake" which I also think is tied to the problem of one design. We talked a lot about Craftsman style homes and I don't see a lot of people wanting to build them and I don't think it is because of the FAR; I think people really want that Mediterranean look and I think whether my neighborhood was under the county ordinance or Cupertino ordinance, consistently everybody builds out to what the maximum percentage numbers are in the ordinance. If we look at simply changing a number to solve our concern about a design, I think we are going to- be disappointed in solving a design problem. I think what we are going to find is just larger Mediterranean style homes. What seems to be happening when people are building these homes, it boils down to what the words are on the ordinance; even though we can have these 7 recommendations and ask the Planning Department to make sure these homes meet these 7 things, what seems to be consistently happening when someone is presenting an existing neighborhood with a new home design and there is controversy with neighbors, you are going to find that when your new homes goes through the planning process, what is really happening in Cupertino today is it boils down to the exact thing that the ordinance says, and I think if we all ask ourselves as Planning Commissioners, when we look at a plan and it is controversial and there are two sides of the street here in front of us, we make our decision boiled right down to the bare bones of that ordinance, and so if the bare bones of that ordinance says 45% plus, the objective of a high quality building material or trellis or bench, all of things get watered down and pushed around and negotiated and the plan moves forward based on a number or a privacy landscaping plan. But it doesn't go beyond that; so if we are looking at changing a number, I think we have to know that is going to be the norm; people are going to take the maximum and do the maximum; that is .what they do now, it is not going to change and when we are faced with issues, all of these good intentioned seven items are going to get watered down and we are going to end up saying, well the ordinance says you can do xyz, so we need to let them follow what the ordinance says. She said she was speaking as someone who has watched development under county and city ordinance for 15 years, someone who has also lived in a neighborhood that will be immediately affected by these changes and she would welcome new design. I know we are not going to get smaller homes, because everyone wants a big house, but I would like to see this done right. We are making ourselves and planners into architectural experts; there is a whole process that would need to be developed that could really push this through correctly but I don't think this is the right way to do it. She said she was.rejecting the proposal. Com. Brophy: • Said he felt it made no sense to change the second floor 10 foot setback surcharge requirement; if anything it should be easier to meet that requirement if you have a smaller first floor. I don't know why we would seriously consider that. I have been going back and forth on this, we have had two previous votes on this in which I voted Yes to move it forward and between now and when we vote I still may wobble, but I think I am leaning toward voting No on this now. 13 - 134 Cupertino Planning Commission 16 September 9, 2008 The going away from a prescriptive to a subjective judgment of aesthetics is just a process that we have great trouble dealing with much more simple issues and when we have an issue that simply cannot be resolved by any defmitive facts, I just think it will make things worse. I would be tempted to, if as a compromise i1' we could look at a smaller FAR ratio for homes that are over 45% second floor to first floor; I might consider that, but at this stage it seems to me that the benefits of modifying the Rl ordinance in this manner are just not worth the gain. Again, I am open to that; it seems to me that we have spent a great amount of time dealing with what axe not the key issues. Let me offer as an alternative way of looking at it, a couple of meetings ago when we had our Lindy L<<ne cases, the case of the Simas house which was essentially 100% and it is probably one of the most attractive homes in the city; part of the reason it works is because the FAR on that is far below .45, so I think there is certainly a case where we could get better architecture through some process; but I guess given the other clauses within the R1 ordinance, I just don't feel comfortable that the gains would be worth it. At this stage, I will likely vote No. Vice Chair Giefer: • It seems to me that everyone who has spoken so far is in favor of promoting our architectural diversity within Cupertino; the problem is, how do we do it; plus protect the neighbor's privacy as well as the person who is building the proposed home. • I agree that the proposal before us does not solve the key issue that I hear from people in neighborhoods, which is the new home is ir..vasive, it is too massive, it is out of scale for the neighborhood. I also agree that your neighbors should not have veto power over the home you want to build. We have heard one resident tc;stify that he was stuck in planning for 2-1/2 years trying to get his home plan approved and because of market situations wasn't able to complete the process. • In contrast to what Steve Yang said about the Architectural Review Board in Palo Alto, perhaps that resident would have preferred us to have had an Architectural Review Board that he and his architect could have made progress with. What is the right type of review for a city like us, and what is the right way for us to pr~~mote architectural diversity within our city. • I agree with Com. Kaneda that if we did change the process for second stories, we should have one process for all residents; any second story addition would need to go through a review process of some sort because otherwise my experience on Planning Commission is that we have processes for people under 45% second story and over 45% second story; they are not going to get it, it will just be too difficult for them to understand it. • I think that one of the things I appreciated about the sample design guidelines we were given from Los Altos and Los Gatos, is both oi' them talked about neighborhood sensitivity in transitional neighborhoods, and I think that i:; key. You need to be sensitive to the style of the neighborhood and what you want to achieve ~,vithout giving your neighbors veto power. • I agree with many of the Commissioners who spoke prior to me; that this is not going to achieve the objective that we want it to achieve; what I would like to suggest for discussion because I think we have a majority on this, that this would not achieve that objective, is what would. Should we send a request back to Council that perhaps we have a review board, if all second story additions go to DRC or go to yin architectural review board. I have always felt that the FAR is either too big for some lot:; or too small for other lots the way it is today. Really it is the architectural quality that we need to focus on. Perhaps what we should ask Council to do is let us review the R1 in tot<<l. As a response we are adding an architectural review board for second story additions. Chair Miller: • The current ordinance was changed in 1999, and the reason was because people were worried about mass and bulk. They were addressing mass and bulk and they addressed it not 13 - 135 Cupertino Planning Commission 17 September 9, 2008 necessarily by reducing the overall floor to area ratio but by instilling stricter setbacks. Before 1999, they didn't have any first floor to second floor ratio, and in 1999 they made it 35% of th4e first floor. There was some discussion about the intent of the Planning Commission at that time; it was really to make it larger than 35% but somehow when it got to Council, it got changed and moved down to 35%. One of the things I am struggling with is we don't want to increase mass and bulk but we are considering making the second story a little larger and the second story correspondingly smaller and staff's view are we going back to pre-1999 by doing this or not. Steve Piasecki: • The effect was to have the greater setbacks to offset the second floor, to push it in. They increased the second floor FAR compared to the first, in effect it was a tradeoff, we will let you have more second floor but you have to set it in with surcharges. As long as you maintain the second story setbacks, you are not going back to pre-1999 because you know the concern about privacy, the window is in the same position as it is with the lower floor. Chair Miller: With respect to the neighbors, these ratios and these things come into play because of our concern for neighbors' privacy and access to air and light. As long as we have the second story setbacks in place, regardless of what the size of the second story is, I believe we have achieved that; we still have the second story can't be any closer to the neighbor than it currently is, and we still have all the requirements for privacy. I am not seeing where increasing the second story makes any difference in terms of how it is perceived by the neighbors. If anything, the neighbors might perceive that the houses are built a little further away; there is a little more space because the first story is going to shrink, meaning that the setbacks could potentially be larger on the first story. The next thing that went through my mind- was listening to Com. Kaneda's comment which was a good one, and that is that if we are going to consider design review, it shouldn't be broken at 45%; so my question on that now, we have more of a prescriptive ordinance presently and we are not doing detailed design review below 45% and my question is how is it working. Are we getting bad or good designs in staff s view. Gary Chao: • A mixture of both; there are decent designs; a lot of people tend to spend a lot of time with the detailing, but the majority are standard development constructions and could use more embellishments, and quality material. If desired, you could design something within our ordinance that looks good. Com. Brophy: . • If we are not doing much review on single family homes, why did it take the last gentleman 2-1/2 years to get his house through? Steve Piasecki: • Said he did not have any facts relating to the case; I can't tell you how it would take so long; it should not have. Gary Chao: • It normally takes two to three weeks to turn a preliminary set of plans back to them. Once it is back to them, it is up to the architect to make the appropriate changes, if any. It should not take more than two months to get out of the preliminary conceptual review process and get to the application phase which takes about one month and a half. 13 - 136 Cupertino Planning Commission 18 September 9, 2008 Chair Miller: • Com. Rose mentioned that her concern was that if we allowed a greater second story, people will go to the limit and max it out. In all other cities around here where there isn't a limit on the second story, in staff's view, does everybody max out their second story. Steve Piasecki: • Said he was not certain he had enough fact;~ to help. If the question is, do people try to max out the total allowable FAR that is a stand~ird response, whether it is a 35% FAR overall or 45%; land is expensive and people don't have the luxury of living in a grand estate; so many people are doing that. In other jurisdictions, the process is much. more onerous than it is in ours; I have seen examples in other communities where applicants are brought forth very attractive designs and have been told they hive to change it and modify it and go through a lot of processes. To your question, generally it is probably true that people attempt to build as much as they can total FAR. I have not seen a second floor to first floor as a rule in other cities, I think we are a bit uncommon in that regard. Chair Miller: • Steve Yang spoke to that to some extent ar~d said that it is not likely people are going to go 100% on the second story. I am not sure I have seen that bear out and I am hearing an architect say that he hasn't seen it in his experience. Com. Rose: • She said to go to Garden Gate where most of the homes that were built in the County where you were allowed to do that are sheer wall, second floor to first. Steve Piasecki: Pointed out that the vast majority of homers in the community are already there; there are 18,000 or 19,000 housing units total, and oi.'those 8,000 to 10,000 are single family; most of what is seen is remodeling activity and it is ~~hysically difficult in a remodel to shape it so that it is 100% because you are usually trying to build something over something that exists. Steve Yang is correct that you are probably riot going to see 100% as a rule; if you are building a new home you may want to take advanta€;e of it more so, and that is Com. Rose's point, is that any new home they are going to try to do that because it is more efficient to build up at the walls. What we are suggesting here is you will have a process and some requirements that will replace what would have been a first story element with other architectural elements to soften and control and make it look more attractive.. That does require that you go through some type of process. Chair Miller: Com. Brophy and Vice Chair Giefer mentioned that perhaps another way to approach this would be to reduce the FAR. I am in agreement with that, particularly .after we had Vye Avenue applications. However, the Council is not, and we have already gone that route. Vice Chair Giefer suggested and sent it back to the Council saying we want to review the whole R1 and the Council rejected that. I am not in :favor of asking the Council a second time to do something they rejected the first time. Why;n I think of what the benefits of increasing the second story over the first story are, I firmly believe that it is a functionality benefit; we are helping the residents in terms of functionality. I believe that staff is correct in that we will be increasing the diversity of styles in the neighborhood instead of having one monolithic style. I like the idea that we are giving people the opportunity to have a smaller footprint; by having a smaller footprint means that there is 13 - 137 Cupertino Planning Commission ~ 19 September 9, 2008 more landscaping, there is more green area and there is more open space for each resident in the city, instead of forcing everyone to maximize their first story and all we see is home after home right up to the setback limits and lots of house and very little open space and green area. The challenge is what kind of process do you put in place because there is a concern that you are not going to get good design and that is a very large challenge. Said it was frightening to think they were not architects, and the DRC is not going to be in a position to look at architecture, and it was mentioned that staff has some architectural skills but they are not formal architects and the last thing we need to do is be putting lay folks in the position of defining architectural style and certainly picking out what, to make sure that we are consistent with a particular architectural style. Steve Yang also mentioned that it was rare that }rou find a true architectural style where the house is totally consistent. Said he felt .he was in the minority, but thought the benefits of increasing the second story outweigh the disadvantages and was struggling with how, if the Commission is concerned with the quality of what they get out of this, how to achieve that and still work with the idea, at least for the applications that come to them. Said he was not unhappy with the architectural styling and the architecture of the houses seen, but they don't see a lot of the houses that staff approves. If there is a benefit to going to a larger second story and the fact that none of our neighboring towns have instituted an ordinance like we have, speaks to the fact that there is not a lot of support in the region, in fact, for limiting the size of the second story. Again, I think that one solution might be to reduce the FAR but we are not at liberty to do that unless we ask Council is they would want to reconsider that particular option. Com. Brophy: • It is true that the second floor to first floor ratio item really strikes me as kind of a strange tool with which to control design and I wish we had better ones. A lower FAR would work because that is what most of the communities we-are comparing ourselves to do. A number of them are at 35%. I have been wobbling on both sides of the issue and I guess at this point, I feel that, while I think the proposal .has merit, I think that without addressing the underlying problem of homes that are too large for the lots. The benefits, given the stress on the community and unhappiness between neighbors, will not outweigh the cost. • Said he was prepared to switch sides and vote No. Chair D'tiiller: • If we made a recommendation to increase the second story and also recommend that the FAR be reduced accordingly, would that be more supported from your standpoint. Com. Brophy: • Yes, but I am not willing to go with a proposed ordinance. I would just send it as a recommendation to the City Council. I have seen that the little caveats seem to disappear when they make it to the Council, so if we want to send it as a recommendation, that is fine, but not as a proposed ordinance. Vice Chair Giefer: • Said she concurred with Com. Brophy, because it would be very easy for them to send it to Council. If they send it back to Council and said they would go with no second story ratio provided that the FAR was lowered to 35%, and hold no public hearings on that, she would be uncomfortable just stating that, although it would probably address many of the issues that come up to often. • Sending it back to Council and saying no, but we recommend that we vote No on this proposal but would like to do is open up FAR or open up the entire R1 because there are other things in 13 - 138 Cupertino Planning Commission ;?0 September 9, 2008 the Rl that need correcting besides FAR. • Said she was not opposed to getting rid of a ;second story ratio, but if you are trying to add 3 to 5% to the second floor, you are just reducing; the bottom floor by 2 to 3%; which is not a lot; it is negligible in terms of the impact of this policy; I don't really see any difference there. Com. Kaneda: • Palo Alto has a strong architectural review F3oard; it got quite a strong diversity of projects. I know their process is set up with view planes, so you can do a straight two story building that doesn't have a setback. Los Gatos also has: a large diversity of architecture; do they have a similar Architectural Review Board type process; I am not familiar with their process. (Staff responded that they do) • City Council asked us to look at the ratio first floor to second floor, but somehow a stronger architectural review process got slipped into the mix. Is that because the cities that we have studied that have a different way of controlling buildings and building styles that seem to have a nice result; is that the consistent theme th:it you found that they have a strong architectural review board. Steve Piasecld: Said he did not know if he would make the correlation directly, but they couldn't think of any other way to handle the issue of the straight alp walls short of some kind of additional process; and they were not comfortable trying to do a prescriptive rule about architecture. They are going through more process; and the process is either some kind of rigorous Design Review Board or Planning Commission revie:w. There is an open public forum process review. We mentioned that we had taken the architectural advisor out of the process and went to the more prescriptive one. You could put the ar~~hitectural advisor back into the process; it would cost about $1,000 per home and he could do a very good job of providing comments. We also try to coach applicants because we see a lot of dumb designs and we know enough when we see a dumb one to try to help people not do that; it is not in their own self interest. We have no authority to force it one way or another and we don't. Chair Miller: • If the main concern is the vertical walls, why not just address the vertical walls if an application has vertical walls in it, then why not that's the trigger point where we require more intensive design. That is what I thought you were saying your main concern is vertical walls. Steve Piasecki: • That is one of the principle concerns and you could try to address it that way, but I think as Com. Rose pointed out, you are going to h~~ve people pushing that limit. I have a two inch offset to my wall, therefore it is not vertical. You have to define what you mean by vertical. Vice Chair Giefer: Commented that she heard at least three people agreed that this doesn't work for them and she said what might be a better use of their tune is to focus on what is the right response to Council. Do we want to send this back to therm and say No, it doesn't work, we want to add an Architectural Review for all second stories to try to promote architectural diversity, because that seems to work in neighboring communities where they do that. Said she did not have a problem sending it back to Council, saying it doesn't work, and that they want to review the R'. The Council ca~i make the decision whether or not they want the Commission to pursue it, and if so, begin public hearings on it. 13 -139 Cupertino Planning Commission 21 September 9, 2008 Chair Miller: • Said Com. Kaneda commented on the design review process; then we talked about having an architect as a possible solution. My feeling on design review boards, I am hesitant to have lay people commenting on architecture that they don't know about, but I probably wouldn't have a ,problem with an architect looking at situations that we define as important, and Com. Brophy and you suggested that if lowered the FAR, that might be more acceptable to Commission. I think we probably have a majority in support of that as well; I think we are headed in the right direction. Vice Chair Giefer: • . Do we want to start getting consensus around those items, because I also heard Com. Brophy say that he is hesitant on sending a recommendation such as that because Council tends to piecemeal what we send to them, and they just take the acceptance of getting rid of the second and not worry about the FAR. Chair Miller: • Asked if there was any reason for them to ask staff to do further research and come back at a later time, or is a motion appropriate. Com. Brophy: • Said he did not think they were at a point where additional staff work would move them any further along. Com. Rose: • I think we can make a motion; what I am hearing and we can discuss this, there is an interest across the Council even to some degree staff, and ourselves on the Planning Commission in making the architectural look and feel of new building in Cupertino have more diversity than it does today. Doing that in a way that enhances neighborhoods and unifies neighborhoods as best it can, and I don't think that is something that is too high to expect of our community Com. Brophy: • Said he was not happy with the idea of committing to an Architectural Review Board; and from what friends in the architectural community have described to him about the Palo Alto experience, the San Francisco experience, he was hesitant to support that process. • Said he agreed that they should recommend they not go forward with the change to the first floor second first floor ratio unless at the very least the FAR is reduced; and he would be willing to open up other areas of R1 if necessary. He said if there was such an interest, he would be very reluctant to emphasize Architectural Review Board based on what he knows. Com. Kaneda: • You were asking my thoughts on the language, and my thoughts were more focused primarily on the architectural issues, so that is irrelevant at this point. Vice Chair Giefer: • Commented on Com. Brophy's comment. If they strike adding an Architectural Review Board at this time, if Council decided that we should review the Rl to clean it up and make changes to FAR, then that might be an outcome of that review at that time if it makes sense because we don't hear a lot of complaints about Saratoga and Los Gatos, and Los Altos that I know all have them, so perhaps it is better for us to spend some time understanding that. 13 - 140 Cupertino Planning Commission 22 September 9, 2008 Chair Miller: • We both know that opening up the R1 could entail a year's worth of effort; personally I don't think that is realistic, not from staff's time:, not from our time and not that the Council is willing to accept. We can ask them again to do that, we have already asked them once and they said No, so I am not sure what benefit there is in going down that route again. On the other hand, if we can identify some very limited areas in the R1 that enhance what we are trying to do here, then I see benefit in going back along that line, and perhaps they would reconsider it at that point. There has been some acceptance about possibly reconsidering lowering the FAR in order to do that; maybe the time when you do lower the FAR is when you have these buildings that have larger secolid stories in order to compensate for what some people feel is greater mass and bulk. Vice Chair Giefer: • Said it was an interesting point of view, but going to the comment about going through the R1 looking for things that would support this language, we would be opening it up anyway. I think the proposal before us now is not on~~ I am hearing consensus on. As the seconder, I would be comfortable striking the point of design review on this if the motioner would also accept that. Com. Rose: • Our comment would be to recommend that we open up the FAR or the entire Rl to look at how to better address design diversity. She summarized the motion: Tie do not recommend that the City Council adopt the RI ordinance amendment regarding the first floor to second floor ratio requirement; but instead recommend that we open up the FAR and closely related matters which impact design diversity. Com. Kaneda: • We are talking about FAR, second story ratio and design diversity. Com. Rose: • Correct, we are trying to achieve design diversity in our R1 ordinance. Com. Rose: • To properly address design diversity, the Planning Commission recommends that to properly address design diversity, they would need tc- examine areas of the R1, FAR and second story ratio. Com. Kaneda: • Said he felt they were talking about three: things; the requirements of the R1 FAR, the requirements of the R1 second story ratio, and how to encourage or increase design quality. Vice Chair Giefer: • What I am hearing is that in addition to FAIZ and the second story to first story ratio, it is the design guidelines that actually need to be strengthened to promote architectural diversity and better quality design and execution within thy: city of Cupertino. Steve Piasecki: • Said there wasn't much in the form of desil;n guidelines in the current R1; it is prescriptive, and you can do just about what you want. 13 - 141 Cupertino Planning Commission 23 September 9, 2008 Chair Miller called a brief recess to allow staff time to compose the appropriate wording for the motion. Chair Miller: • When you just address design diversity, that is a staff concern, but the applicants that come up here, their main concern is design functionality. I think there is a major word missing in there. The issue here is that the small second story limits design functionality or limits functionality period. Staff has a concern about design diversity, but the intent of changing the ordinance I think is primarily from a functionality standpoint. Steve Piaseclci: • The flip side of what we are talking about is just the uniformity of design that you are getting now. We get variations on a theme, but it's much the same thing. Vice Chair Giefer: • If our recommendation is to deny this proposal, what is missing is we don't specifically address the area we were told to look at which is second floor ratio. She suggested rather than talking about residential functionality, to put back in the key of this reviewing FAR and perhaps be very explicit of its impact to second floor area ratio, She said they could get rid of ,that ratio, and only need one ratio (second floor/first floor ratio). • Asked the Commission if it is explicit enough that their intent is to review FAR as part of this. Steve Piaseclu: • That would be the wording "and consideration of the overall impact of the allowable floor area" which is FAR. Where it says "overall" take out the words "in consideration of the allowable floor area and second floor to first floor". Com. Brophy: • Said he thought there was a good case to be made for being clear that is what they wanted to look at. Once again, if they say No, it would be a dead subject and move on. Motion: Motion by Com. Rose, second by Vice Chair Giefer, that the Planning Commission does not recommend the proposed approach to deal with the second floor to first floor ratio. The Planning Commission recommends that the concern for design diversity and functionality are better addressed by evaluating a more comprehensive design review process for two story homes, and consideration of the allowable floor area ratio and second floor to first floor ratio. (Vote: 4-1-0; Chair Miller No) : None No meeting. Housing Commission: ~l~o meeting. No report. No. meeting. 13 - 142 Cupertino Planning Commission 23 Vice Chair Giefer: • One because it is not specifically stated here; and as we are and other p s, we are going to have abutting uses to one ano ' that wherever po 'ble, we are not chopping up par ' ots July 8, 2008 EXHIBIT E mgress/egress between vaned ownership.

Kaneda, to recommend approval of the Master Plan as amended. ('Vote: 5-0.0) Chair Miller declazed a recess. 4. MCA-2008-03 Municipal Code Amendment to the Single Family Rl Ordinance City of Cupertino (Section 19.28.060) regarding the allowed ratio of the second Citywide Location floor building area compared to the first floor building area. The Revised Ordinance will consider adjusting the allowed ratio to facilitate greater azchitectur~l diversity, but will not consider increasing or decreasing the total allowed building area on an Rl lot or changing the required second story setbacks. Continued from the May 13, 2008 Planning Commission meeting. Tentative City Council date: Not Scheduled. Gary Chao, Senior Planner, presented the stalff report: • Reviewed the background of the application for discussion of the Rl Ordinance first floor to second floor ratio requirements, as outline~I in the staff report. On May 6, 2008 the City Council amended the Planning Commissioc~ work program for 2007-08 to include a limited review of the Rl ordinance, specifically regarding the size of second floor ratio compared with the ground floor, with recommendations to lie presented to the City Council by October 2008. Citywide notification was mailed out as well as the creation of an information webpage with hearing information, related resources regarding RI and the current regulations ~ Relative to the review fi-amework, the focus will be considering whether there should be any adjustments to the required ratio of the second floor size to the ground floor. We also think that if the Planning Commission desires some adjustments, the rule pertaining to the total allowable exposed second floor wall height should also be considered since it goes hand in hand. Currently the ordinance requires second floor to not exceed 45% of the ground floor, or 750 sq. ft. whichever is greater. In addition., the existing ordinance also has a provision that says all the perimeter second floor walls shall not be over 6 feet in height exposed up to 50%. ~ He emphasized that it was a limited review, meaning for the viewers that the Council did not want us to look into tweaking the building areas or second story setbacks, and, they want to look at ways to look within the existing ordinance infrastructure and see how we can facilitate greater architectural diversity. The City Council has expressed concerns and some concerns expressed by the residents that the exiting It1 Ordinance limits diversity of architecture. As part of the last Rl process, one of the changers at the time was to allow for a slight increase of the second floor ratio from 35% to 45%; at that time it_was a reasonable accommodation to 13 - 143 Cupertino Planning Commission 24 July 8, 2008 allow people to have a third bedroom upstairs to have enough room to have reasonable functionality of a second floor. In this case, the consideration is different; it is not to allow people to have a lazger second floor per se, but the focus should be on allowing people some flexibility of the ratio so that other types of architectwe could be fitted within the envelope. We have been hearing that the existing 45% second floor to ground floor ratio restricts, even though it covers mass and bulk, but it prevents other types of azchitecture such as Victorian style, true Craftsman style, and the fact that the 50% second floor wall exposwe also contributes to that limitation. As a result, what we are seeing more is the repetitiveness of the "wedding cake" architecture as the dominant architecture and there is not going to be a lot of flavor and character, if you will that one would agree from a community like Los Gatos or Los Altos would have. Because of the restrictio0n on the size and second floor, people are trying to increase their ground floor to accommodate for the size of the second floor that they want. It is counter intuitive, people don't necessarily need the square feet, but they are providing it to get the sufl•icient room they want upstairs. Leslie Gross, Assistant Planner: • Reviewed the various architectural styles in Cupertino, which are illustrated and detailed in the staff report. She also reviewed the design guidelines of other communities such as Los Gatos and Los Altos which are outlined in the staff report. Gary Chao: • Said that staff believes that in order to achieve architectural diversity, one doesn't necessarily have to tweak the setback or the floor area ratio; they are proposing ordinance solution that by incorporating appropriate design review process and the finding design principles that one can apply, that you can achieve architectural diversity through that process. Therefore homes may be allowed potentially to exceed the 45% second floor limit and/or exceed the 50% second floor exposed wall rule if they are designed appropriately. Staff is suggesting that the Director of Community Development may grant the approval to allow the second floor to exceed the 45% and at the same time to exceed the 50% wall rule provided that the following principles and techniques are met: -~ Enswe appropriate architectural interest and compatibility with neighborhood design theme and character; -a Enswe appropriate building mass and scale; -~ Design with azchitectural integrity on all sides of the structwe (maintain symmetry, proportion and balance). It preserves the existing 45% rote, but if one wishes to exceed that, we could facilitate that process in exchange for better architecture and more diversity. The principles aze to enswe appropriate architectural interest and compatibility with the neighborhood design in terms of theme and character, and some of that are adding visual interest such as balconies, porches, overhangs, and trellises, many of the things already touched upon. The decision of the Director may be appealed to the Design Review Committee. Staff recommends that the Planning Commission recommend that City Council adopt the Rl Ordinance amendment as proposed with the provision to also cover the 50% maximum second story wall exposwe rule. Chair Miller: • Asked staff to review the process and the type of review that goes on today for two story residences in Cupertino. Gary Chao: • All two stories are discretionary review; it is staff level approval; however, we would advertise 13 - 144 Cupertino Planning Commission 25 July 8, 2008 the proposal to adjacent neighbors or neighbors within 300 feet. When an application is received, story poles are required to be erected, notice boards to be posted in front of the project site to disclose a floor plan and a rendering of the development. The adjacent neighbors are given a two week comment period before staff entertains approval or a decision; a decision of the Planning Department is ap~~ealable to the Design Review Committee. The process for a second story greater than 45% is the same as what is being done now; it has been noticed already. It will be treated at ;;tall level with neighborhood notification. Staff is suggesting that the decision of the Director can be appealed to the DRC. Presently there are no design guidelines or instructions how to treat some of the plain facades that may be prevalent in a more traditional architectural style. Staff is suggesting that there be a special ;process and review process for that purpose with detailed guidelines for people wishing to exceed their second floor ratio. Vice Chair Giefer: • Recalled than when the Rl was reviewed, she and Com. Miller were the only two Commissioners still serving who were part of the process; the Committee determined that they wanted it to be as prescriptive as possible to eliminate the necessity of design guidelines and to incorporate as many of those features directly into the Rl . Steve Piasecld: • Said that when an applicant comes in and is informed they have some options, you can come in with a 45% second floor to first floor ratio; it is essentially one-third of the second, two- thirds on the ground floor. We were usuig the ground floor building azea to act as that softening of that second story building wall. You can come in that way; you still notice your neighbors and they still have the opportunity for input. The alternative is you can go higher than that; essentially you are stripping away that softening element but you need to replace it with something else, and staff has described all the something elses that we would expect. We still notify the neighbors, but the applicant should talk to the neighbors before they apply for one of the options to make sure their preference isn't just privacy is the most important issue. You would replace it again with other elerr~ents, and then you would hopefully work it out with your neighbor before you come into this city. We would review it, notice the neighbors and if the neighbors want to appeal it to the DRC, it would be resolved in that format and/or the Planning Commission. Staffwill not be in the middle. Com. Brophy: • Has staff received any feedback from architects or local home builders relative to the proposed changes? Gary Chao: • Said they have spoken to several local architects who have done work in town and they all agree that if you were to tweak the second floor 45% ratio without tweaking the 50% rule, it is not going to work. Many of them admit what we have now; they have their system down in terms of satisfying their clients needs, and at the same time designing something that is acceptable to staff. However, they do recognize the fact that it is pretty much it; everything is going to look like a wedding cake and that precludes their ability to provide any other type of architecture and that the direction they are headed toward is a positive one. Com. Brophy: • In a lot of the town the wedding cake style of architecture is so predominant that people would find exceptions to that on new lots to be objectionable. I was wondering if that was.a problem. People get unhappy if you want to build something that is different from what the neighbors 13 - 145 Cupertino Planning Commission 26 July 8, 2008 have; and I was wondering whether or not we are opening up a new can of worms here. Gary Chao: • We have heard that before as well. That is why the term wedding cake came about. We get it both ways; often times people complain about repetitiveness of new style of architecture which is prescribed by our current ordinance; but then there are some who are resistant to the different theme or style of architecture. It is important to note that a lot of the things we are discussing are to still respect the theme and character of the neighborhood. It is the main focal point of this proposal. Steve Piasecld: • Said it was important to note that what is being suggested is if you want to go in this direction, you need to replace it with something like this. Com. Brophy: • Said that coming back from the most recent DRC meeting that he and Vice Chair Giefer attended, they both had some second thoughts as to the vote we had on allowing exception to the second story setbacks. He said he would feel better if they are going to allow lazger second floors; they could add a clause that makes it cleaz that the policy is to be skeptical of exception requests, especially for those homes that are at or near the maximum FAR Com. Rose: • Asked if someone today wanted to exceed the second floor ratio as it stands, do they have the option of asking for an exception, but it will not fit t he 45%; is there a process for that or is it automatically not allowed. Gary Chao: • There is a process for that; it would be an Rl exception request; it would go directly to the DRC instead of staff level review. We haven't had a formal proposal as such since the last ordinance change. A lot of the times people's fear is that the word exception is not really accepted to neighbors once it is being noticed. Now we would likely entertain something like that if the architecture is superior; however, being that there is no case study in the past, it will be interesting how the DRC is going to treat that as well. Com. Rose: • Using the same argument you are using, you are suggesting a change if it was an attractive house that had treatments and landscaping, and side wraps and high quality materials and preserve mature landscaping and positive conversations with the neighbors; then it could very likely happen for that person. Steve Piasecld: • Said it could be approved; it would need two exceptions: the second floor to first floor, plus the 50% wall plane and you have no rules or guidance about how to judge that. All this would do is give you some rules and language that would back up the granting of that. It wouldn't be called an exception. Com. Rose: • If this were to move forward as proposed with the typical noticing of the neighbors within the 300 feet, would it call out the change to the second floor area ratio as something that is different about this house? 13-146 Cupertino Planning Commission 27 July 8, 2008 Gary Chao: • Said it would be part of the legal description of the project on a notice that goes out. • Explained the 50% wall plane rule. If yoit take all four walls of the second floor; the linear walls and stretch them out, you will get a total lineaz feet of the perimeter walls; the ordinance says that 50% of it has to be 6 feet or less in height exposed; and it goes into specifics as to how that could be accomplished. It cannot be just a trellis or lattice structure or some type of fake architectural skirt or roof around the ground floor; it has to be an enclosed structure down below with its roof going up to cover that wall up to 6 feet. You can have in theory two sides of the wall completely flushed all the way from ground floor to second floor; however, the other two have to be extremely recessed a~~d indented. We don't normally see that happen; usually it is a combination of some vertical wall on the same elevation and some roof being used to serve as that cover Com. Kaneda: • Said he was under the impression that you could not have a two story wall anywhere at any time. Steve Piaseclci: • Said that people have been complying with that at3er a lot of explanation from staff. It is one of the most difficult things people have to comply with. . Com. Kaneda: • Said that he generally supported what you aze going for, but one of the issues becomes, there is a fine line between some of the projects you shared that were bad and some of the projects that you shared that were very nice and it boils down to architectural aesthetics. It is a good idea to ask the Planning Commission and City Cot;~ncil to make their judgment calls; that is the big difficulty. Palo Alto has an ARB that is famous; the buildings are nice, but difficult for the architects to get a building through the pro~:ess. He said even though he liked the concept, how would it be done in real life? Steve Piaseclci: • Said it was a good point; this is where the rub is; you end up bringing in a greater level of design review and process and you are corre~~t, and the communities that exercise this level of design review, it can be torture. • For the record, staff did not bring this forwani, but we are trying to give you a method that will be between the two extremes, and the only ore we can think of is we have a higher expectation of design, the proof is in the pudding, talk to your neighbors, bring it to the DRC or staff first, and if it looks like some of the pictures shown, we are likely going to approve it and anyone can appeal it. If it is anything significantly less than that, then we are not going to approve it; it will go to the DRC, and you are likely going to have a fight with your neighbors. The biggest rub here is people spend a lot of motley designing houses, and they don't want to get too far down the line before they know that they have a winner. It can be 10% or 15% of the project costs, a half million dollar home is F~retty expensive. You aze identifying one of the real issues that comes up. Com. Kaneda: • Is there any value in coming up with a sliding scale based on lot size for the 45%. Steve Piasecld: • Said there is; the Commission can make any recommendation to the Council; you can look at other options such as sliding scales, lower FA:[ts, but it was not the direction from Council. 13 - 147 Cupertino Planning Commission 28 July 8, 2008 Com. Kaneda: • Said he was concerned about matching the predominant style of the neighborhood. Some of the neighborhoods have a lot of variety and the Eichler neighborhoods aze also attractive. Said he was concerned about putting in a set of rules for neighborhoods, especially for those that already have two story wedding cake, Mediterranean style, developer-looking California suburban homes which aze now locked into that, and all the homes in that neighborhood theoretically have to match that style. Steve Piasecld: • Said it was an excellent point, and said it was offered on numerous occasions to neighborhoods who have strong opinions about being one-story ranches or Eichlers. A case can be made if you can show that there is a dominant style, and that is what the super majority of the neighborhood wants to live with; however, it is extremely difficult to get the super majority to agree. Com. Rose: • Asked questions how many homes aze torn down and rebuilt per year, single family tgwo story residences; (staff responded about S0; major remodels with removal of a large portion of the house would be between 100-ISO per year.) • Are a lot of builders building less than they are allowed to based on their lot ratios and second floor ratios; is there a trend towazd people being more concerned about a certain style of home or are they prioritizing how much house they can get on the lot based on the ordinance. Gary Chao: • Said the current ordinance does an adequate job in allowing a reasonable size of houses compared to the lot size; we are not hearing people complain about why they can't build a bigger house, but most of the houses coming in aze waxed out. What we are hearing is people saying they wished they could have done something different; you are designing my house for me; the home owner doesn't have a lot of flexibility, but doing as prescribed. Com. Rose: • Said that the photos of homes illustrated a style of home she did not see a lot in Cupertino; and wondering if you have, what I tend to see is the Mediterranean style and I am curious how that is going to look with the proposed 50% second floor ratio. Although the homes were attractive, she did not see that as a preferred style within the development that tends to happen residentially in Cupertino. She questioned if it was misleading to put that out there because that may not be what will be seen if the second floor ratio is changed. Gary Chao: • Said there were some Mediterranean styles that work; they tend to be boxy, but there are appliques and features that one could incorporate into it that will address the concern. He said that many of the Mediterranean homes in Cupertino are not true to form. The genuine style have a lot of recessed windows, cantilivers, attractive materials that go into the design. • He said that indirectly the design is locked in when a plan set is approved, especially atwo- story proposal, all the features are part of the approval. A covenant could be entertained to disclose to the future property owner that there should be special review if something on the house is changed. Steve Piasecki: • Said that people max out to the 45% overall floor area ratio; if the house sells and sells again 13 - 148. Cupertino Planning Commission 29 July 8, 2008 and the new property owner applies to put in a shed and his request is denied. You pre-empt all flexibility when you go to the maximum FAR, and it creates problems because every new owner wants to put their stamp on it. Chair Miller opened the public hearing, Matthew Klein, Cupertino resident: • Back in the 1930s, 40s to 70s, we didn't build 3,000 square feet second stories over 1,000 square feet first stories; we didn't have hou:>es like this. A few people on Prospect decided to was offended. Hence, back to Com. Rose's question, why can't you build this house in Cupertino; because if you look at the second story you will see that it is more than 45%, it is more than SO%; in fact if you have it over tr:e enclosed porch, call it 125% or 130%. We have 125% roughly second floor to first floor; it vicorporates an enclosed porch which is the state of design goal of the Cupertino Planning Commission but there is no affected enforcement of it or affected encouragement of it because if you do a 45% second story over something like this enclosed porch, you cannot build it. This i;s impossible today to build a building like this in Cupertino. Why is it people aze building monstrosities/wedding cakes? It goes back to Com. Kaneda's comment, this 50% exposed wall is very complicated but it is the single most objective thing and the single most important thing that is driving the wedding cake design. It is in fact a defacto additional setback of the second wall plane over the first wall. Forget the general setbacks 20, 25, 15 feet surcharges; in order to get that 6 foot exposed on your second wall, you have to come up with a structural feature against it, typically a roof line, so every new building monstrosity in Cupertino, we ;ire forced to look at people's roofline at the mid horizontal plane of their building. I don't want to look at your roofline, I don't want to look at your molars, but why is it that every single building we are forced to look at people's rooflines, because the architects and designers aze forced to give you that feature in order to satisfy the exposed wall requirements. Peopte don't want to build monstrosities and wedding cakes, they have to because people in Cupertino have children; if you want to add a second story to an existing building, i.e. a remodel ~~vhich is different than new construction and you want to have your children live on the same floor as you, you want to have enough square footage to do that. But with an existing ranch style L-ranch, you are limited to 45% of your existing; typically these houses have 6,000 to 8,000 square foot lots, but to do a remodel you have to satisfy 45%, and with requirements for staircases and foyers, you are going to spend a lot of money to get 700 usable square feet upstairs; and the reason is because the 50% rule requires an imposed setback from the first plane. The existing house doesn't have sheer walls, or a foundation sufficient for that so you have to remove the roof and spend a fortune to get a small second story addition. The family decides to sell and move to another city. The next buyer purchases the home and demolishes i~t and builds a monstrosity home. We have no design guidelines for windows. Delete the 50% exposed rule; delete the 45°ro; owners know what to do; no one is going to build a 4,000 square foot second story over 1,000 square foot. You can't do it because the setbacks won't permit it and the FAR won't permit it. Hence, regulations and setbacks on top of the setbacks are ridiculous; it is producing the monstrosity buildings which have been in the last ten years, and we scratch our heads and ~avonder why we have this mess; it is because of your design guidelines. Jennifer Griffin, Rancho Rinconada resident: • She questioned why they were reopening the Rl ordinance; it is completely different than what was discussed in March. How did we ~~vind up having this go to 50% and breaking up the sheer wall plane. This is contradictory to :Etl; we are basically reopening the entire thing. • She expressed concern about the monster homes and creating big boxes, and Rancho 13 - 149 Cupertino Planning Commission 30 July 8, 2008 Rinconada is going to have to have a special zoning, Rl-R, just lake Fairgrove, the Eichler community. We have lots that are less than 5,000 square feet, my house is 800 sq. ft., now if we ever put a second story in, I am committed to putting in second story setbacks because I respect my neighbor's privacy. We have a balcony going up; across the street and that has completely upset the neighbors. Gary Chao designed a wedding cake house which has made the neighbors okay with the balcony, and the balcony looks right into all ow homes. I saw the first story going up today; my neighbor across the street with two small children is going to have a balcony looking directly into her kitchen and backyard. The reason why we have RI today; if we are going down this road, let's reopen the entire thing; I have spent hows and hours in this pity in these meetings discussing Rl, so let's take it to the entire limit; my brother when they put a second story on their 1892 Victorian home in Los Gatos, it took 9 months to go through the code. Let's do it; let's have every possible little building restriction; let's limit the colors to six colors like you do with the Victorian in Los Gatos. In my neighborhood of Rancho Rinconada we need second story setbacks, we need neighbors' privacy to maintain our lovely wedding cake homes and some of ow old Rancho homes. Matt Itamkar, Cupertino resident: • In favor of application. • I would like to urge to support and change the 45% rule. Here are some of the issues that were not discussed. • When you make the second story larger compared to the first story, that gives you a bigger back yard; I believe a bigger back yard goes into both more green space and better quality of life for yow family. It would also be less strain on city resources as parks. The other reason I believe we need to do that is Vice Chair Giefer referred to purple pipe. The purple pipe will allow a bigger back yard gives you better more room to do rainwater captwe on a small well within your site and use the water for irrigation and landscaping. Second story, the current regulations will discowage solar panels because the angle of the roofs that come into the walls so a smaller first story which would be the result of this regulation being passed will create smaller roofs and smaller foundations which is more resowce conservation. Finally, if a potential homebuilder has a choice between the property on our side of the border vs. San Jose that goes to Cupertino schools, they would chose the San Jose side and take the city of the opportunity to get funding and property tax upgrade that comes with more transactions within the city. For these reasons, I believe we should go ahead and increase the 45% rule. Dennis Liu, Cupertino resident: • I am a developer and currently working with an azchitect to design a new house in Cupertino area and I just found out it is very difficult with the 45% law; my azchitect said it was impossible to build a two story house with three bedrooms on the same floor. As you know most of the family in this area that still have more than one child, so with this 45% rule, you can only build a maximum of two rooms on the same floor: We have forced the family to separate the children on a different floor, which creates a difficulty for some of the families. I work with many realtors in this area and they told me that they aze all facing this problem; the young family moving into the area really like the education system in Cupertino and have to sacrifice and put the young children on different floors. I think this is a tremendous difficulty for many young families, and I agree with many other architects; I would like to support and have this amendment to increase the 45%. ~ He said in return for being able to do up to 100%, he said it was worth the effort to have a higher level of azchitectwal review. Terry Brown, Cupertino resident: • Said he was in favor of eliminating the 45% rule. It is another example of efforts to reduce 13 - 150 Cupertino Planning Commission 31 July S, 2008 good architectural design to mathematical formulas; and it will fail every time. Relative to the 50% rule, he said he hoped they were talking about the wall plane issue, not just changing the FAR upstairs to .5. (Stcr,,~''said the SD% was wall plane area) Said he was generally opposed to architectural review of any sort. I think that I prefer to have architects practice their trade; people build :homes that they like the looks of, not necessarily some one else's choice; but I am certainly answer that question you put to the last speaker in pretty much the same way; if you can get ricf of the .45, get rid of the mathematical formulas, then I guess we can put up with increased architectural review. Seema Mittal, Cupertino resident: • Said she designed homes in Cupertino, Palc Alto, Saratoga, Los Altos Hills, all neighboring cities, and it is interesting how different the cities are and how the products of architecture are different in different cities. Most of the issues have been addressed between the people who spoke here and the Commissioners. • Said she supported removal of the upper story restriction and having design guidelines, because presently Cupertino does not have diem. While it is subjective, there is nothing you can point to when working with your client. However, what happens when you change the rules in the middle of the road, we were building to 35% upper story, then a couple of years ago we started building to 45% and now inching up. There are certain homes that have already been built on that premise; they were 1,000 square feet on the upper level and they assumed that the neighboring house would d~~ the same. As a result, privacy views, sunlight, solar devices, are at stake. It is difficult to bring up those objections because they are not quantitative; they are qualitative. It is easy to enforce numbers but difficult to enforce something subjective. I think if there were graphic design guidelines and if the Rl code said that neighbors' concerns regarding view, sunlight, privacy; because there are options how you design upper stories; you have to keep the cor.:text in mind; you have to see what is going on in the neighboring houses; you can't just completely ignore it and say that you meet your numbers, so I have met the design criteria and I will sail through. • Said she had no objection to the increase, provided there are graphic guidelines and provided that the planners can enforce views, privacy. Chair Miller: • Pointed out that they did not change the second story setbacks; so your comment about it is going to change access to light and privacy i:~ not completely on target, because the setbacks for the second story are exactly the same as th~;y are today. Seema Ii'tittal: • Said that the RI did not address the upper st~~ry balconies. You can have 1,000 square foot upper story balcony because it is not counted in the FAR and have a huge upper story mass, and it can't be questioned quantitatively bec~mse it adds to the mass but doesn't add to the square footage. Chair Miller closed the public hearing. Com. Rose: • Said she appreciated the speakers providing input, and was in favor of keeping the status quo. • We are tasked with only to consider the current second floor ratio to first floor ratio and the argument that is asking us to look at this concern is that homeowners, the current situation encourages homeowners to increase the size oj~ their first floor to get the most they can out of their second floor, which allows a certain numt~er of bedrooms, children on the same floor. • The second thing we are addressing is the current ratio also encourages sort of one style of 13 - 151 Cupertino Planning Commission 32 July 8, 2008 home which is referred to as the wedding cake style, and it is not allowing people to design and build other styles of homes. I wish I could feel confident that what we are discussing tonight would change some of the architectural houses we are seeing coming up in Cupertino. I wish that the list of treatments that are proposed to soften a house that perhaps has a larger than 45% second floor would always be included in the architectural plans. Unfortunately I am skeptical for two reasons. I live in a neighborhood that used to have no requirement for a second floor setback or ratio, so I am surrounded by homes that have that block feeling on very large lots. I think that is indicative that when you aze given the opportunity to build as big as you can, you do. Staff validated that point and a speaker also said he would build as big as he can. I am not certain this is the answer to getting smaller homes; generally it is just an open door to build lagger homes that have more of a bulk appearance and that you are going to have to cross yow fmgers that the builder and the staff are going to be working in sync to use architectural features to minimize the bulk of that house. I just don't feel comfortable with that much gray area when it comes to new development. What staff was saying about the 45% rule must be changed with the 50% rule, I am not comfortable with the fact that we have separated those two, and I think that it is difficult to say a house has to have a friendly presence to the street. I think everyone could have a different idea of what that means, so although I like all the ideas presented to soften the look of a house that potentially has a second floor that is greater than 45% of the first, I am not confident based on what I see happening currently, that those suggestions will be carried through in an attractive manner. I don't think we are going to see homes different than what we are presently seeing. It needs to be thought of a lot differently and a lot deeper than it is. If we are going to open up the R1, we should be looking at the much bigger pictwe than what we are trying to do today. Com. Brophy: • I would agree that I would prefer to see a more comprehensive look at Rl, but he Council has decided otherwise. Given that theoretically it has always been possible for a home builder or applicant to ask for an exception, I don't see that this change is a huge change; apparently home builders have chosen not to exercise the right to ask for an exception or they feel that is not an area that can open up, I think I would with some hesitation, flip on the other side and think that it would hopefully lead to improved quality of architecture. • The one change I would make from the proposed ordinance, is include a class discouraging exceptions for second story setback requirements for homes that aze at or near the maximum FAR. Vice Chair Giefer: • Agreed with Com. Brophy that there is an avenue available to builders today that if they do want a building larger second floor and reduce the reduce the first floor, that the process does exist today. I share the same concerns that Com. Rose had that it isn't really going to make a big difference; we are still going to see people move forward in the easiest path with the lease resistance which is the status quo today. ~ Recalled as one of the Commissioners when the last RI Ordinance revision was done, one of the reasons they went to a very prescriptive format, we did have design review guidelines, and it put staff in conflict with the property owners quite a bit of the time, and property owners we frequently heard that they were delayed by staff, so when I think about putting the design guidelines which when we approved the Rl, which I don't think I voted for the current Rl, when we did approve that as a body, the major sentiment by many Commissioners was we needed to be highly prescriptive because otherwise the property owners felt that staff was dictating what could be built; which is some of what we are hearing today as well. 13-152 Cupertino Planning Commission 33 July 8, 2008 Expressed concern about putting staff bacl; into the point of conflict with the public, which could occur, we don't have design guidelines; I find the suggested language conflicts and will create greater confusion with our current R:l policy. I think that we are not directed to review the 50% wall ratio and so if we are going to go back to Council and say yes let's do this and we recommend further review of the 50%, there are a lot of other things I would rather review in the Rl than the 50% wall ratio and the change to the first second story ratio. I think there are a lot more compelling things we should :look at in the Rl. When we moved forward on the last Rl we said we felt as a body we should. review it every five yeazs; we are at the five yeaz mark, and perhaps we should open up the entire Rl as has been suggested. Put more thought into design guidelines. I would like to see more varied architecture in Cupertino; it is possible today. My final comment in reading all the other ordinances that staff provided us for part of our review for this evening, I was struck by ho~v all of the cities were really community focused; they acknowledged that the people wanted to move into a specific neighborhood was because they wanted to be part of that neighborhood, and if you care about a neighborhood and you want to be part of that neighborhood, you ai~e not going to disrupt the neighborhood; you will improve your property because it will vis a iris improve the neighborhood, but our Rl doesn't really care about the neighborhood; it cares t~bout the rights of the incoming property owner to come in and build whatever they want to build, and if it is an attractive building, I support it. I think we need to do that. If it is a spec home that is being built as cheaply as can and as large as possible, then I think it needs greater scrutiny. If we were going to move forward on the Rl., I would support taking more of a neighborhood buy-in process in the neighborhood orientation with where we go. Said she did not support what is shown today; I like the idea of further design scrutiny, but that is available today. Com. Kaneda: • Conceptually I support the amendment, but ax this point I don't support it. I take exception to the way the ordinance is set up now; I thinb: the wedding cake design pushes azchitects into doing mediocre design at best. • Talking about sustainability, there are somE; real sustainability issues involved in that too, because if you are forced to go in, there is a resource issue, there is a structural issue, the sheer walls can't cant' out; the framing gets more complicated. It forces an architect to do things that are structurally unnatwal, and so I think we have built a lot of buildings like that that haven't done a great service to the community. On the other hand, the whole reason that was put in place was because of some pretty egregious two story massive buildings that were built in Cupertino and those in their own way are as bad or worse architecturally. I am willing to look at a change that will allow people to do buildings that aze two story and styles that are different, but I think it really needs to be thought out that there has to be a lot of care and tune and effort put into putting the guidelines together, to make sure that it is done. ~ The other thing is I suspect that it is going to 17e frustrating for the architects that are designing buildings in our community because I.think a lot of times what will happen is you will be working within the rules still, but you have this layer of people telling you it doesn't look good because of this and this change or design. I am concerned; I am not sure how we will do it, but evidently a lot of the other cities have figuredf out how to do it. Look to the other cities to see how they are doing it, and find the best pr3ctic:e among them. Chair Miller: • I have never been in favor of limiting the :second story, for many of the reasons that the speakers have addressed. • Matt Kamkaz discussed the fact that you get more green space and you have less runoff to deal 13 - 153 Cupertino Planning Commission 34 July 8, 2008 with; from that standpoint it is more of a green design by allowing people to go up. It also promotes better solar usage because you get more access to roof area to do that, as opposed to having the little roofs here and there that you can't put a significant solar system on. I think that this change doesn't, if the concern is that it affects privacy or it affects access to sunlight, I don't believe that is correct because second story setbacks are not being adjusted; and that is the governing rule that affects both the privacy and the access to sunlight, and we address privacy with different treatments of the windows and address it with landscaping and the fact that there maybe a vertical wall plane, it is going to be 15 feet from the property line, instead of 5 feet from the property line. In effect you are increasing the space between yourself and your neighbor if you chose to go vertical and to my way of thinking that is a good thing. If you go back east, all you see is vertical buildings and I have looked at this in Boston and Connecticut and in New York and other places, and the difference between there and here is the horizontal space between the buildings. The further you are away from your neighbor, the less objectionable the higher elevation is when you deal with houses. The 50% wall plane, I agree with staff, we cannot do one without the other and since the Council did not direct us not to talk about the 50%, I think that is appropriate; otherwise we can't put this into effect. I agree with Com. Brophy that if we do this we want to discourage changing giving exceptions to the second story because then we would be compromising the privacy of the neighborhoods and their access to light and sun. The comments that Matt Klein made, specifically with respect to remodels is so on target, that in order to do a remodel on a small house today, you basically have to teaz it down and build a whole new house because of the limitations. The limitations we impose are far too onerous, so we are forcing people to do more development on their property than they really need to do. The other issue that seems to come up here is neighborhood compatibility and that has always been a difficult area for me because I don't see anything wrong with eclectic and if you go into some older neighborhoods in Willow Glen where all the houses were built by different builders and every house is different and yet the neighborhood seems to fit together nicely; it is quaint and the landscaping works; and even though the houses are different the azea looks great. Willow Glen's resale values are up there with Cupertino's. What has a lot to do with it, is how well that azchitectural design works there, or the non-existence of architectural design, because the fact is when we talk about neighborhood compatibility, some people take it to the point of what I call neighborhood conformity. Every house has to look the same; and we have had people come up and argue in neighborhoods where most of the neighborhood was ranch houses built after World War II and argued that it has to be a ranch house in the World War II style and I just don't agree with that. I don't think that adds to the character of Cupertino. The other issue that staff brought up as another strong reason for moving ahead on this is that we are losing the style and the tradition of Cupertino houses to some extent because you can't build them under the current regulation, where you could be more compatible if we allowed more flexibility. Summarized that there were two Commissioners in favor of the changes, and two against, and one on the post. Com. Kaneda: • Said that he was against the changes, because the regulation needs to be thought out more and cleaned up. If there is a way we can do that here, he would be willing to look at it. Chair Miller: • Asked Com. Kaneda if staff came back with a specific set of guidelines for the Planning Commission to review, would that be acceptable. 13-154 Cupertino Planning Commission 35 July 8, 2008 Com. Kaneda: • Said it would be acceptable if staff presented a specific set of guidelines for further review. Com. Rose: • Said the examples everyone is giving of thi;~ new plan are homes that people azen't wanting to build in Cupertino, and I don't think it is a :matter of not being able to because as pointed out, there is an avenue to build any kind of home you want; you just have to get an exception and the process that we are looking at would include additional DRC review anyway. • I am wondering if we should list some certain design styles, because I would be comfortable with that. My concern because what I see is a predominant Mediterranean style home and I see it where there were not second floor ratios that were built 10 to 20 years ago and I see a consistent desire to max out whatever building size you can do. I don't see this interest in bringing in new design and maybe if I could just do this; and I am not hearing from staff that people are asking how they can get their two story Craftsman or their New England Connecticut style home; I am hearing that everyone wants to build as big a home as they can and that tends to be the Mediterranean style so that is what concerns me. So if we want to go specific, why don't we list out some typical ;styles that are comfortable and if you want to task staff, they could outline what is a soap box home and that could be an example of how you could have a larger ratio than 45% of the second floor. Chair~MiIler: • I am not sure why not; the first comment we made is just get an exception; and therein is the key issue because you have to spend a lot of money to do a design these days. You go to an architect and he wants $30,000; if you go in :For an exception, and the owner has to put up the money, the architect will say you have 50% chance they will let you do the exception, and he will say it is not worth the money, because they are on a timeline and they are on a budget and they don't have money to gamble with. T'he comment "just get an exception" is a very significant hurdle; that is why people don't da it. Com. Rose: • It sounds like we are still asking people to go through a design process; if they say they put their trellis; and there is argument whether it i:s a trellis; they are told to go to DRC. Chair Miller: ' • The difference is you can do some sketches and work with staff and the cost is not that high• that is the issue why people don't go and people will not go for an exception. It is too expensive. Com. Rose: • Said she felt it was still not adequately thought out. Chair Miller: • We have a difference of opinion on that. The other thing I don't think we want to do is say we are only going to allow certain styles; then we ,sre getting into the job of being architects. Com. Rose: • Said she agreed, and knows what the azchite:ct does; but I also feel that what is going to happen if this happens; it is not that people will say they don't have to build such a big first floor; I can build a big first floor, I can build a big second floor and as a speaker mentioned, what is happening it is lovely to think that people are running around with their plans saying neighbor, I just got the lot and here is what I am going to do; the reality is that it is not 13 - 155 Cupertino Planning Commission 36 July 8, 2008 happening. My feeling is that before we jump into something like this, there needs to be more discussion around what we are trying to achieve. Because what this will achieve is stucco walls from the first floor to the second floor. Chair Millers • The reality is that it is happening because everyone who does a second story house has to put a rendering in front of their house and the story poles, so that no neighbor can possibly miss it. Even though some people go and talk to their neighbors, at this point what we force them to do is, you don't want to talk to your neighbor, you want to stick it our in front like a big advertising sign. If the neighbor becomes upset when he sees it, he will come knocking on your door; and if he doesn't knock on your door, he will come down to the Planning Deparhnent and say that he is upset about what is going up there, do something about it. Nothing is getting past the neighbors anymore; we fixed that when we changed the ordinance 3 years ago. Com. Rose: • Nothing is getting past the neighbors but then when they bring it to our attention we tell them what the ordinance allows, and if they do not like the ordinance, the community has to get together and make their neighborhood a single story only neighborhood like Fairgrove. If the ordinance allows it, it is very rare that you are going to get a situation in which the DRC or this body is going to overturn something if the ordinance allows and you will argue that you are selling houses to people and they are looking at our ordinance and saying if I can build 45% then I should be able to build 45%. If we put it in the ordinance, then people are going to expect it. We are relying on this list of design treatments to soften it, and that is when we get into the architect's business that we were saying we didn't want to get into. I am not saying this is all a very bad thing, but it is a big thing and it is something that needs to be thought about and if we are really trying to have houses like Gary put on here, which I am not really seeing unless you go out to Rancho. If we really want that and that is what we are working toward, then we need to think about how we are working towards that; we don't just change a percentage. Com. Kaneda: • Said he recently went through a home remodel; the architect said not to do two stories and he now has a sprawling house because he followed the ordinance. Com. Rose: • If we are going to change this ordinance, Iet's be careful about. Maybe Chair Miller's suggestions are right, maybe we tax staff with defining all these different details for each type of house we are going to get; but I think the reality is, is what people really want to build is a much bigger Mediterranean house with stucco walls. Vice Chair Giefer: • Has staff sat down and said with the setback requirements that we have, what is the maximum second story percentile that is achievable? (Sta„~f said it was 100%) • Has staff evaluated the conflicting language of the proposed modifications to the ordinance based on the rest of the language in the Rl, because you are giving different directions. Steve Piasecld: • Clarified you could even go more than 100% if you take out the 45% rule, second floor to fast floor. You have two distinctive processes in the ordinance; that is why you lost the conflict. You can follow the old rules or you can come in and follow the new rules in which case you 13-156 Cupertino Planning Commission 37 July 8, 2008 are going to have greater design scrutiny based on these words in the ordinance. Some Commissioners feel it needs to be more than words, maybe we need some design guidelines so that it is more specific We don't have a problem with that; the examples we looked at in other communities were developed by azchitects but they have a much longer more scrutiny in the process; they cost a lot of money, none of which were part of the tasks that came from the Council so the Commission has a couple of options. You can say we really can't deal with this the way it is; we need more design guidelines and you need to authorize every expenditure to get that done and then we will feel more comfortable with it. You could also task staff with it and they will come back with pictures and the best we can do; homes don't look like they fit in Cupertino. You could give that a month try. We could take a shot at it and provide more specificity based on the comments from this Commission and the public. The other option is you can say that we cannot get agreement, ;send it back to the Council without agreement and we can explain the debate, because you had a good discussion and this is so typical of Rl; there is so much passion that goes into it; we heard it the last time we went through this; everybody has an interest in RI. It couldn't hurt to wait 4 to 6 weeks and let us take a shot to drill down on some of the questions and issues to see if we can fmd better language that will provide better levels of comfort. Vice Chair Giefer: • Said she did not feel it accomplished the goal; I think we are going to have a lot of unintended consequences of this because we are taking a quick swag at this; which is what I think it is; let's just take the dial and move it over here now and wait 5 years and see what is billed to the city. I don't think we can do that. Steve Piasecki: • Asked if the concern was that they would erid up with stucco boxes with concrete roofs with appliques and a few trellises. Vice Chair Giefer: • The public is going to feel as though we are back to the pre-existing ordinance where the public is going to say that staff is an impediment to building; we cannot get anything approved in Cupertino. Everybody's opinion of existing; vs. future is different; I am not saying we don't need to re-think this; I am just saying that tl;.is will not solve the problem that we have been asked to address and solve; and that is why I am not supporting it. I am completely supportive of saying let's take a look at FAR, having meaningful design review put back in, and I would support that. I think that just trying to fix this one little ratio isn't going to achieve what we wanted to achieve. I think we are going to have unintended consequences. Chair Miller: • Said he understood what they were saying; and would rather try to address the problem than not address it, and Council has not given them the latitude to open the entire Rl, so it is what it is and there is a consensus for letting staff give: it a try. Motion: Motion by Com. Brophy, second by Com. Kaneda to let staff take another look at it; to include some language about strong discouragement of exceptions to second story setbacks requirements for any changes, Steve Piasecki: • Suggested that the motion provide at least 6 vreeks to go back and restudy it. Relative to the exceptions, eliminate them; with this route there is the variance option which is a harder standazd to meet; discouraging exceptions does;n't work. 13 - 157 Cupertino Planning Commission 38 July 8, 2008 Second: Com. Kaneda Com. Kaneda: • Does it make sense to get some outside professional help to try to come up with your guidelines; staff is understaffed and there are no staff architects;. and in my mind a fair amount of this is highly architecturally related. Steve Piaseclci: • That is what the other cities are doing. The Los Gatos guidelines were developed by our architectural adviser at considerable expense and considerable time. The concept doesn't really change from city to city a lot; we can try to call from the examples we have given you and other examples; maybe we can put something together. If we are not successful maybe we would still want to have an architectural adviser come in and look over our shoulder. We will look into different options to try to do it with less expense and time, If that fails, you can send it to the City Council and say you really cannot do this without doing more elaborately and opening the whole R1 box up. It would be a year and a half and a quarter of a million dollars. Chair Miller: • Maybe there is a middle alternative; perhaps staff does their best shot at coming up with some guidelines. We have heard tonight from at least one person who is an architect; I know of others who do business in Cupertino who would be happy to meet with staff and give further input and perhaps refine it, so it wouldn't take a lot of tune from any individual architect to do that. Steve Piaseclci: • Said they would give it a try, and likely would seek their architectural adviser on an hourly basis (Vote: 3-2-0; Vice Chair Giefer No; Com. Rose No.) 5. Dispassion of the pre-review option for the development prop ls. Steve Piaseckrpresented the staff report: • Said that the\C cif sent it back to the Planning C fission asking that they expand the noticing and look ome other options, specifi y the one seen in So. Vallco that in the cases of some lazger de ments, perhaps so a sort of expanded community review process is appropriate; otherwise tak other look all the options for eazly review. We have given you the verbatim transcript whic as make it cleazer exactly what is intended. This is one given the lateness of the hour, we make a greater outreach and with more notice, we could get more developers top cipate. Keith Murphy: - • Said the proposal s baffling as to what its real ben twill be; I understand the idea of talking with dev opers about future applications they may ant to bring in front of the city and how may the community might feel about that or how s eels about that. I have a real problem it sets up the city for a lot of legal problems, would lik a city attorney's input, and if feels it will be more of a problem for the city or is it rea oing to solve the pro ms that we think it is. Is the city attorney going to be part of this pro s to be able to monitor some of these meetings and see if they really are going in the right direc which the Planning Commission and City Council would like them to; or are they going to be more of a 13 - 158 ExxIBT~rs BEGIN HERE L' L l O l ~ / l0 ~ X13 CHAPTER 19.28: SINGLE-FAMILY RESIDENTIAL (Rl) ZONES Section 19.28.010 Purposes. 19.28.020 Applicability of regu]ations. 19.28.030 Permitted uses. 19.28.040 Conditional uses. 19.28A50 Development regulations (site). 19-28.060 Development regulations (buildin=). 19.28.070 Landscape requirements. 19.2.8.080 Permitted yard encroachments. 19.28.090 Minor residential permit. 14.28.100 Two-story residential permit. 19.28-1 1 O Exceptions. 19.28-720 Development regulations-Eichler(R1-e). 19.28-130 Development regulations(R1-a). 19.2$-1-40 Interpretation by the Planning Director. 19.28.010 Purposes. R-1 single-family residence districts are intended to create, preserve and enhance areas suitable for detached dwellings in order to: A. Enhance the identit}~ of residential neighborhoods; B. Ensure provision of light. air and a reasonable level of privacy to individual residential parcels; five hundred square feet of development, including grading and structures, occurs on an area with a slope of thirty percent or greater. D. An application for building permits filed and accepted by the Community Development Department (fees paid and permit number issued) on or before October 2, 2007 may proceed with application processing under ordinances in effect at that time. (Ord. 2011, 2007; Ord. 2000, 2007; Ord. 1954, (part), 2005; Ord. 1886, (part), 2001; Ord. 1868, (part), 2001; Ord. 1860, § ] (part), 2000; Ord. 1834, (part), 1999; Ord. 1635, § 1 (part), 1993; Ord. 1601, Exh.

An additional five percent of lot coverage is allowed for roof overhangs, patios, porches and other similar features not substantially enclosed by exterior walls. B. Floor Area Ratio. The objective of the floor area ratio (FAR) is to set an outside (maximum) limit for square footage. The FAR shall be used in conjunction with the residential development standards and _vuidelines in this ordinance in determining whether the mass and scale of the project is compatible with the surrounding neighborhood. 1 . The maximum floor area ratio of all structures on a lot °'--~" -'-~ is forty-five percent. 2. The maximum. floor area of a second story _'--~~ is forty-five percent of the existing or proposed first story floor area, or seven hundred fifty square feet, whichever is greater. 3.

Interior areas with heights above sixteen feet, measured from the floor to the top of the roof-rafters, have the mass and bulk of a two-story house and •',-r,-'-n-r--~ are counted as floor area. a. If the house is a two-story house, this area will count as second story floor area; otherwise, the area will count as first floor area. C. Design Guidelines. 1. Any new t~~-o-story house, or second-story addition to an existing house, shall be generally consistent with the adopted sin__le-family residential guidelines. The Director of Community Development shall review the project and shall determine that the following items are met prior to design approval: a. The mass and bulk of the design .',-,~-:1~~~ is reasonably compatible with the predominant neighborhood pattern. New construction shall not be disproportionately larger than, or out of scale with, the neighborhood pattern in terms of building forms, roof pitches, eave heights, ridge heights, and entry feature heights; .. b. The design shall use vaulted ceilings rather than high exterior walls to achieve higher volume interior spaces; c. There shall not be a three-car wide driveway curb cut.
